Quote from samforey12345 :The Aprilia RS125 is a 2-stroker, with probably about the same power as a 600cc 4 stroke engine. Difference being, the 2-stroker is bloody expensive, unreliable, and very very dirty. Having said that they give you a thrill to remember when hitting the power band xD You're saying that a RS125 is as fast as gixxer? ASD
My bad, that must be some high-quality 4-stroke engine engineering xD. EDIT: The gixxer is a motorbike.. that explains things :P
Quote from samforey12345 :Those autograss buggies can be bought for 4000 you can buy something like that ready to assemble engine for 5000£ * Attached images
Thats essentially a wider version of an autograss special by the looks of things, presuming the engine will go in the back of course.
