Actually, in terms of putting a rider to the test, the performance 250 two strokers are more ambitious than a 1000cc. Any dwinde no matter how useless a rider can go fast on a 1000cc. It is just a matter of twisting the throttle, power will make up for inadequacy .

But the two smoker must really RIDE his machine. Working with it to ride that fine line of exquisite poise which is the essence of motorcycling. And if he can do it, the 250 will probably be faster than the 1000cc in mediocre hands , provided the road be twisty. Of course , on a straight road, anyone on a big cruiser can go fast. There's no ambition in that.

Whats the cheapest / best value for money aftermarket upgrades to make your litte 250 four stroke go harder.

I'd recommend a HRC two stroke conversion kit for your CBR250.

I can't recall the part numbers off the top of my head, but if you call a Honda dealer, they should be able to help you out.

[Mr. Peanut]

Anyone who can find a crank for an NSR250 has ambition enough...

[SuperDave]

Agreed with Ixion - respect for those who can ride a high strung 250 two stroke properly.

your very right unfurtunatly

Some good stuff listed here...I was running my bike totally standard but got sick of the sewing machine noise....so i fitted an after market exhaust....no noticeable power gains...no noticeable loss in torque down low...but a little bit of engine braking has been lost with a huge gain in aural appeal!! I now squeeze a few more kays out of a tank...but that's mainly because i don't need to give the bike as much throttle to hear it.

Derestrict kit for speedo and ignition.
Iridium plugs
98+octane booster
Fully balanced and tuned carbs and custom airbox
5w 50 oil (Visco 5000 or similar)
also check the clutch plates when you do the oil change - if need be when you do the oil change, do a 20K flush with diesel oil.
The rest i would leave until you have a bigger bike
