It's a tricky one. I contradict myself on this subject because I love the thought of a 250 being a 250... then I rode TYGA's 300!

It does make you lazy though, because when you are used to wringing the 250's neck to get anywhere and then suddenly have almost an extra 1/3 more horsepower, the first thing you exploit is rolling on the throttle rather than jumping on the gear-shift.

Bear in mind though, that as previously mentioned, 71.5 hp is all coming out of standard parts. All TYGA effectively does is match the 150 transfer ports to the 250 cases and clean them up.

The scope for tuning the 300 is limited really by the crank more than anything else, and don't forget, there is a limit to what the stock carbs are going to flow - the RS is running 38mm carbs, the NSR only 32mm - it makes a hell of a difference once you start trying to extract the last horse out of the motor.

NSR motors with RS barrels (there have been a few) still only throw out HP in the low to mid 70's because of the two limiting factors I mentioned above. The RS makes the power through RPM, ignition, big carbs, ram-air, and eventually exotic fuel. Also remember that the RS that shared similar components to the NSR was discontinued over 12 years ago. Those models were only ever knocking out power in the 80's anyway. It's the latest generation 72 degree stuff that's making the 90-100hp now, not the 90 degree stuff.

As our guest rightly says though, the NSR isn't an RS... then again, a Ford Focus 1.8 isn't a WRC car! But well sorted, in the hands of a competant rider/driver, they are the next best things for the money! They can both be made to handle, they can both be made to go, and they can both win races against more exotic machinery... I've seen it done!

I for one would like to see ram-air as the next 300 option! :lol:
