I contacted yamaha motors here in vikhroli. They said 1.24 L on road here in mumbai. Thats too much for a 150cc mil.. I was thinking of buying it as well, but the price tag took it away from me. If you need power and comfort I suggest you get CBR250R (with ABS /without ABS - again a personal choice IMO)
Believe me, a tourer (CBR250R) is indeed a tourer, so its riding position is good to travel long distances. Personally I have tested old R15, cutting corners is easy with it, engine is really smooth.. Never tested a CBR250R though.. If you want hands on review, you may PM kauzy for it. He has CBR250R... I would suggest you to take a test drive..
But I have met you personally before and I think Yamaha R15 V2 will suit you, it is indeed fast and smooth, no vibrations at 110kph, didnt try to go above it... depends on you, if you want more power, you should go for a 250cc engine...Speed will follow it with smooth handling, its Honda ofcourse....
Yamaha R15 V2 should have been priced a little close to 1.10L on road and it would have been a perfect take... Many R15 owners would kill me coz of my comments.. But its price thats what I am comparing, no doubt, R15 is a damn good bike...
