I think bike manufacturers need to drop the 300's and go hard at a 450 class of sport bikes. It is the pinnacle of off-road performance in dirt bikes so why it hasn't translated to the street is bizzare.
GSX-450R, CBR450R, Ninja450R, Yami R45, RC450 etc
Am I the only one thinks this class of bikes would completely take over?
well, the ninja 400 hasnt really done all that well....its just a ninja 650 with a weaker motor from what ive briefly read.
the problem with bumping up the CC on all the 250/300 class bikes is where does it end? well ...its when it is just shy of their 600cc class or the 650cc sport touring class and they just blew it by making their beginner bike redundant.
lets just keep in mind these bikes were launched to be beginner bikes (in north america), friendly on insurance and easy to ride.
the honda 125 and ninja 250 took off great and they serve their purpose.
then everyone bumped it up to 300cc (or 296cc in reality...just like the 600cc class is really 599cc...but whatever)
and now with KTM launching the 390 (373.2cc) with a slightly bigger bore.
keep adding a little more stock power here and there and watch your rates keep climbing too.
i wouldnt be surprised if there was a big bore kit launched eventually for the KTM 390. they have a big bore kit for the exe 350 to bump it up to 390cc so its only a matter of time.
if i were to guess, it would be the same concept that is used to upgrade as the sportster, you can buy a 1250cc kit for your 883.
anyway, what im getting at is this has just turned into the battle of the biggest-little bike....
start off, learn, upgrade when you are ready and can afford it.
