  1. Yamaha Xmax 300 coming to Thailand?

    Speaking of the Nmax. Yes. It has fantastic brakes. Also lately been doing more two up riding and not just with my gf. For example. I had my gf on it and a friend who weighs more than 200 pounds so it was 3 up and the bike felt very stable considering. Then today, had another friend on it with me. Normally he rents PCX's. Handled very nicely with good pickup. And we went about 12 kilometers 2 up. Rory weighing over 180 pounds and myself at around 170. Then I discussed the two up riding with another good friend who recently got an Nmax 155 and then sent his 150 PCX upcountry for family use. Richard's take on the Nmax is it is rough riding compared to some other bikes such as the PCX. (while the upcoming Xmax should have a really cushy ride). This is due to the firmer suspension of the Nmax which makes it have a harsher ride. However, he did comment that it is much better than the PCX 150 for taking on heavier loads such as I've been undertaking lately. Richard is thinking of getting an Xmax when it is available. But we both agree that the Nmax is a fantastic bike.
  2. Honda PCX v Yamaha N Max

    About 1.5 more horsepower which amounts to roughly a 10 % increase in power. The displacement of these two engines is about equal. But I do believe the PCX has just two valves whereas the Nmax has four. The Nmax also has variable valve timing. This amounts to the engine not working very hard at low revs to maximize fuel economy. But when you really jump on the throttle of the Nmax the valves stay open longer allowing more efficient combustion of the fuel. So with the Nmax you get a lot of the same kind of high performance benefits of a racing cam. The process is explained here. The result is the Yamaha Nmax engine has a lot of high tech performance built into it that lesser motorbikes do not have. You will especially notice the difference when you take the two bikes on the highway. Get an Nmax up to say 110 kph and hold the throttle open. The engine keeps giving and giving whereas the PCX is just about done. And by the way, those 13 inch wheels offer much more stability than one would expect. I had my Nmax up to 90 kph on Sukamvit today and it felt just about as stable as it felt when I was doing 40. Factor in the very superior brakes and you end up with an incredibly capable machine that does just about everything very well.
  3. Honda PCX v Yamaha N Max

    I believe either one will do quite well. I weigh about 75 kilos and my gf weighs around 45. I hardly know she's on it. I have a good friend who weighs around 275 or so, and he feels it's got plenty of power, even after I mentioned to him that the Yamaha XMax 300 is likely to soon come out. In fact, I've had him on mine with me and it was much better than one would think for short hauls. The Nmax has roughly 1.5 more horsepower than the PCX 150 at approximately the same engine displacement. So it's going to have the advantage, especially for 2 up riding. And its brakes are simply phenomenal and this will translate out to a decisive edge while riding two up. At 80,000 baht, nothing else comes close to the Nmax 155.
  4. Honda PCX v Yamaha N Max

    They do look small. But the proof of the pudding is to actually get on and drive. I've had mine up to 120 kph (75 miles an hour) and I felt it was more stable than my girlfriend's Honda 150 PCX at 115 (which is all it will do). My girlfriend's PCX 150 is in my favorite color (PCX red). I can drive it anytime I want, but I haven't in over three weeks. I feel sorry for it. It's an excellent bike, but I view it as the ugly sister no one wants to ride. The Nmax is simply that good.
  5. Honda PCX v Yamaha N Max

    A good friend of mine bought an Nmax right after I bought mine. He loves it so much that he sent his PCX150 upcountry to be used by the family of his GF. But--last week he told me he felt his bike had a little vibration problem so we swapped bikes to see if there was a difference. He felt my bike was much smoother. Still, he does not find the vibration to be all that annoying--it's just something he's noticed. I feel my Nmax is a bit rough at extremely low parking lot speeds, especially when I compare it to my gf's PcX 150. But it's no big deal. Overall my Nmax 155 is simply out of this world. In my opinion it is far in front of everything else as the absolute finest all around bike one can have for the Pattaya area AT ANY PRICE. My gf's PCX 150 is a nice machine, but my Yamaha Nmax is a Porsche sports car in comparison. In my opinion it's been totally engineered from the ground up to take advantage of its 13 inch wheels. As everyone knows here I am not a fan of smaller wheels. I love those 18 inch wheels on my Yamaha SR400. But the Nmax is a different breed of cat. I believe Yamaha paid extremely close attention to detail and balanced this machine just right for the smaller wheels. The struts are just right that strengthen the chassis. Then there's the superlative brakes. Disks on both front and rear with anti lock. (which is unprecedented for an 80,000 baht "scooter type machine" (it's an underbone , not a scooter per se) So the smaller diameter wheels are able to initiate a turn very quickly. And the driver knows he's got fabulous brakes so he tends to be braver going through turns. The bike is extremely responsive and agile with loads of usable power on tap. So the driver simply tends to go faster in all conditions. I drove my friend's Aerox which he loves (of course). It's got massive (for a 150 c.c. underbone bike) front and rear 14 inch tires that make the Nmax's tires look rather small by comparison. Compared to my Nmax the bike seems more planted. You can feel those heavier wheels at work, which is the way things should be. But the Nmax really wants to dart from side to side and turn turn turn while still being very stable. And, unlike the Honda Click I test drove a couple of years ago and put my results on You Tube, the Nmax with its 13 inch wheels is MUCH MUCH more stable at 100 kph and above. The (Click has 14 inch wheels but its tires are narrower).
  6. New PCX 150 - Prices gone crazy?

    Or you can get the Yamaha NMax for a lot less than the PCX150 although it's still higher than the Aerox. Both the Aerox and Nmax share the same 155 c.c. Bluecore engine which is 10 percent more powerful than the PCX150. My good friend just bought the Aerox. I test drove an Aerox rental he got a couple of weeks ago while he drove my Nmax. The main reason he did not buy an Nmax is he thinks the styling is too much like the PCX's. Although theoretically the Aerox should be a tad faster than the Nmax due to its being lighter weight, I felt my Nmax was a bit snappier. The larger tires of the Aerox made it seem "more planted", but it was also a bit less nimble. I would think the larger (14 inch) tires of the Aerox would make it more stable at high speed on the highway. But nearly all my driving is in the Pattaya city environment. And the 13 inch Nmax tires are more than stable enough for the kind of driving I do. Besides...I've had my Nmax up to 120 kph and at such speeds I believe my Nmax is more stable than the PCX150 with its 14 inch tires. And although the Aerox undoubtedly has excellent brakes the Nmax has even better brakes. The 13 inch tires allow me to initiate turns quicker than larger tires do. Plus, I have total confidence in my bike's braking power and this confidence tends to make me go a lot faster than I would on a bike that has inferior brakes to mine. Actually even though it's an automatic, the Nmax is a very sporty and fast bike to drive in the Pattaya area. For many it's roomier and more comfortable than an Aerox. And here's the real kicker. It has a 6.6 liter fuel tank to the Aerox's 4.6 liter tank. At around 80,000 baht I think it's the most fun, best all around bike one can have in the Pattaya driving environment at any price. And it's supremely practical. Then again, beauty is in the eyes of the beholder so if my pal prefers the Aerox to an Nmax, all the power to him. Both are great bikes. And at the substantially higher prices that are now apparently being charged for PCX's, it's now no contest between Yamaha and Honda. Just pick your flavor.
  7. Bike for tall man 125 to 150cc

    In my opinion the best bikes for Pattaya and the immediate surrounding area are the Honda PCX 150 and the Yamaha NMax 155. Although I've seen a lot of good reports here about the Yamaha Aerox 155, its riding position is not equal to the NMax's. Only a few months ago, I bought my girlfriend a new PCX 150 and she loves it. Needless to say, I can drive it anytime I want, but I don't. The reason is my new Yamaha Nmax 155 is so much more fun to drive. And safer due to its anti lock brakes and disks on both the front and rear. Also, a good friend of mine who is a follow condo co-owner in my building used to love his Honda PCX 150. Then he bought a Yamaha Nmax 155. I got the word from him yesterday that he sent his PCX 150 up to Issan for his brother in law to use. So here you have it. The PCX 150 is an excellent bike for all around use, but the Nmax 155 is simply spectacular.
  8. Grand Filano vs PCX150

    Absolutely. I just came back from Washara Marine having the oil changed on my Nmax 155 and while they were doing it, I went to the main showroom, looked at the big bikes, and also talked to a young salesman. He owns the Grand Filano. It will only do 100 kph, if that, which is what I heard from other sources. He is hoping for the Yamaha 300 X Max to become available in Thailand but he is now thinking, November, not April. The reason is he can tour Thailand, driving to Koh Chang for example. I'd much rather drive to Koh Chang in my Honda Civic than any bike. But this trip is much more doable with the PCX 150 than a Grand Filano, and it's even more doable with the new Yamaha Nmax 155 although if you gotta do it on a bike, it's better to have at least a 300. But anything short of this long a trip, the PCX 150 can do it all, while the Nmax 155 can do it all even better than the Honda PCX 150. Even with those (fat) 13 inch tires, the Nmax is even more stable on the highway than the PCX 150, it has the best brakes in the business compared to anything anywhere near this price range (80000 baht), and it has a more powerful engine due to the variable valve timing and four valve head to the PCX's 2 valves. It also has a lower center of gravity and much more responsive steering. But at least the PCX and the Nmax are close while the Grand Filano is entirely out of this league entirely.
  9. Yamaha Aerox 155cc Launch

    I didn't mean to send you to all those places I used to hang out in. I have my own private google setup on my web site. So if you were to go to my alphapro main page or many other pages on the site there is a search engine box at the bottom. YOu can use it and type in Yamaha Nmax 155 or you can go to the main Google search engine (outside my site) and type in "Honda PCX 150" or "Yamaha Nmax 155" In both later cases I should be in the top 10 of Google.
  10. Yamaha Aerox 155cc Launch

    If you can find my in depth review on my alphapro web site, I have compiled stopwatched acceleration times for the PCX 150, the Nmax 155, the Honda Click 125, the Yamaha SX 125, the Yamaha Nouvo Elegance 135, etc from 0-50 kph and 0-80 kph. The Aerox uses the same engine as the Nmax 155. But it weighs slightly less. This means you can compare the Nmax times on my web site to all these other bikes, and then figure the Aerox will do a tad better.
  11. Yamaha Nmax owners call out

    `Look up on Google "Jack Corbett Yamaha Nmax 155" I have done an extensive review of the PCX 150 vs my new Nmax 155. Done some top speeds on both bikes and stopwatched times from 0 to 50 kph and 0-80 kph. I bought a Honda PCX 150 for my gf and later got myself an Nmax 155. I prefer the Nmax although the PCX has its advantages. But if its performance you are after, the Nmax is definitely the top dog. One thing I do want to mention against the Honda Forza and similar machines is this. THey would be much more difficult to pick up and muscle around than an Nmax or PCX 150. Three times now I've gone down to the MAX Muay Thai stadium to video the fights. It's nearly impossible to park right in front of the stadium--it's that crowded with bikes. First two times I was able to wrestle my Nmax over a curb and up on a small concrete slab. Even so it was a tight squeeze between the other bikes. The third time I had to park across the street in an area filled deep with sand. The Nmax was just small enough and light enough that I could pull the bike through the sand, muscle it above curbs, and squeeze it between rows of tightly parked bikes. I do not think I could have managed this with a Forza or Sym 300, Sym 400, etc. Also, the last time I took my gf along. Another condo owner took his gf along but they used motorbike taxis. Without half trying we beat the other couple to the restaurant even though the motorbike taxi driver likely knew all the short cuts. This Nmax has a combination of features in a relatively small light machine, and it is very fast.
  12. Yamaha Aerox 155cc Launch

    I can assure everyone that the NMax is a terrific machine in heavy traffic. My Yamaha Nouvo Elegance was the same width of the Nouvo SX, and now that I'm used to the NMax subjectively it is every bit as good at getting through the tight spots. It's also very good at highway speeds. Plus it has a lot better acceleration and far superior brakes so when you factor these two attributes in it's even better than an Elegance or Nouvo SX in city traffic. And as far as the Aerox is concerned I sat on both at the dealership and the Nmax has better seating position for me. And, it's got better brakes than the Aerox. That much larger fuel capacity is a very huge deal for me. Having the best brakes could be the difference between life and death. So based on this criterion alone it's superior to its stable mate.
  13. Yamaha Nmax 155 outperforms Honda PCX 150

    You are not paying close enough attention to what I wrote. Note that my reference to the R3 is enclosed in parentheses ( ). My reference is to my SR 400 being said by some to be capable of 90 miles per hour. I only referred to the Yamaha R3 as having more than 40 h.p. was to dramatize the difference between what amounts to a de-tuned 400 c.c. engine and a significantly lower displacement engine that produces nearly twice the horsepower. I personally think the R3 represents a lot of performance for the dollar and would be loads of fun to drive. But here you are suggesting that the R3 has a possible top speed of around 112 mph. Well, perhaps. But I once had a 1981 BMW R-65 horizontal twin. It only weighed 408 pounds, was a 650 and it had 50 horsepower. The top speed on it was about 105 mph. And as I pointed out my Honda 450 produced 45 h.p. which is slightly more than the R-3, and I'd say about 100 mph was about it. Now...if I weighed only 45 kg instead of the 75 I actually weight and I laid absolutely flat on the tank, and I removed the tach and the speedometer on such bikes, well maybe these inflated claims can be substantiated. The only thing is in the real world one does not lie absolutely horizontal to the tank, etc. etc.
  14. Yamaha Nmax 155 outperforms Honda PCX 150

    Now that sounds like a good idea.
  15. Yamaha Nmax 155 outperforms Honda PCX 150

    I'd say that across the board there's a lot of inflated claims for top speed. For example, I remember Honda claiming top speeds for the likes of a CB 160 back in the sixties of over 80 miles per hour. Or a CB 350 producing 36 horsepower of around 103 mph. I had a CB 350 and I'd say on average it was good for about 90 miles an hour although on a good day in the right conditions it might go 95 mph. Then I got a CB 450, and it was good for around 95 to 100 mph, and this with 45 hp to the 36 hp of the 350 Honda. I had not one, but two, on off road Honda XL 185's. Top speed was usually around 70 but on a good (tail wind?) day it might see 75 mph. And although the Yamaha SR 400 has a very modest power output at 24 h.p. (whereas a 321 cc. Yamaha R3 has 42 h.p.) I've seen a lot of people claim it will get up to around 90 (albeit slowly). Mine has never gone beyond 120 kph (75 miles an hour), but there are no real level spots on the road from Pattaya to Rayong and before I can get the bike to its absolute top speed too much traffic congestion occurs so I have to back off the throttle. I'd be happy if I got a legitimate 80 miles an hour out of it. As for doing a zero to 100 kph run----that's roughly zero to sixty. THis would be a very meaningful stat. The problem is with a small scooter type bike it will be difficult to hold and manipulate a stop watch for this entire speed range. This would not be nearly the problem for much faster powerful bikes that can get up to 100 kph in 5 seconds or less. And again....on that stretch of road on route 36 that ends where I pull a you turn at the International School, driver's license center, one is either going uphill or downhill practically all the way. Also when you are winding a 125-150 cc. undertone bike out to 100 kph and beyond, it takes a much longer distance to get up to such speeds on such small bikes and by the time you are up to 100 and trying to get up to 115 or 120, traffic congestion starts to become a huge obstacle, especially when you factor in the unfathomable, unpredictable bad driving of so many Thai drivers. Unfortunately in these conditions with these smaller motorbikes doing zero to 100 kph stop watched times is a very dangerous proposition.
