agreed.... but honda does what it wants to do.... it woulda been VERY easy for them to increase the bore n stroke of that thing to make 400cc's... but they wanted to compete with the ever popular ninja 250.


Watched that vid earlier and went.... hey i know those roads... i ride them like every weekend.... <3 the snake and other parts of Mulholland.

suzuki quotes the SV at 370 lbs dry, so ad the weight of all fluids and likely the battery. The honda weight is wet, ready to ride at 359.

Very interesting. I liked the vid and the information on the motor. I'll bet you can flog it until the sun don't shine.

^^^^ i think you will HAVE to flog it untill the sun dont shine
but besides the fact that it is a 250 single it sound to be more "advanced" than the 919
in should have atleast been a parallel twin or even a inline 4 would have been sweet.
little tiny pistons little tiny valves all reving to somwhere in the 18k mark would be so great

an inline 4 250 would have no lowend torque which would ruin the whole... easy for a beginner rider to learn on stigma such a bike has.

I see their reasoning for a single 250 it makes perfect sense, the XR250 i have in the garage is a fuggin tractor, makes for tight technical stuff a breeze thanks to its low end... translate that to street gearing, and you have yourself a great round town bike thats very easy to ride and modulate the throttle.

A parallel twin would of been nice... its probably the best compromise between hp tq and round town ride-ability in that size of cc's , but the single 250 is obviously more simple of a design than a twin would be.


And REGARDLESS of engine setup... 250cc's on the street is what it is - theres no replacement for displacement!

I think a parrallel twin or a V. That would have been the e ticket.

oh yes for sure.... i dont know why honda tooled up another 250cc motor, when they have the badass lil motor known as the VTR250 sitting right there for em.... vtwin FI'd liquid cooled 250cc with great hp and tq sitting right there for them... slap some fairings on it and they would be good to go without having to retool much at all.

Those numbers on the ninja are quite high... every dyno chart out there says about 25Ish hp, and 12.5ish ftlbs

Picture: Kawasaki - 2010 Kawasaki Ninja 250R Dyno



Id imagine the honda 250single is pretty much the same on hp, but more on torque. And its very possible to get these numbers out of a single... my CRF250X makes ~ 30-32hp and 18ftlbs.

This is exactly what I was thinking. The VTR's V-twin would have been perfect!
