The YZ250X also has a wide-ratio gearbox. Further investigation reveals that it has a taller third, fourth, and fifth gear, and the same first and second gear ratios as the YZ250. The stock gear spacing is good for off-road competition with a close first, second, and third. There is also that little extra in fourth and fifth for higher-speed sections. If you plan on riding this bike for longer distances or in desert-type racing, you might desire a little more top speed. An easy option would be going down one or two teeth on the rear sprocket. The clutch was smooth as butter and reacted very well, and just a quick stab of it easily gets the rpm up.
