Not homologated on public roads, only reserved for competition, does not respect the highway code in any way!
A very good kit at low prices whose reputation is second to none, this kit is renowned for its performance, its torque/high speed ratio, its solidity and its more than reasonable price. It is 49 millimeters in diameter, fairly advanced diagrams, it has (as usual on new motor parts cylinders) the grease nipples under the side transfers, the kit is very clean and finished as always on Top performance kits.
We recommend it to those who want something to ride every day (Outside France because not approved) and those who stunt because this kit is really torquey thanks to its normal exhaust, its diagrams and its bi-segments. Very solid thanks to its MINACROM treated cast iron. Its color is quite sober with its semi-shiny black.
We will be able to make it reach even more power thanks to a preparation because the piston is really not worked enough on this type of kit. The cylinder head is in high compression chamber, hemispherical and polished, beautiful material which also has the top segment polished hard chrome domed to be placed at the top of the piston.

As an option, we offer you a STAGE 1 preparation, this preparation includes a selection of the best part from our stock, a marked improvement in the shape and the exhaust diagram as well as a special retouching of the cylinder skirt and the piston. for better sweeping/filling according to our best tests. An improvement in lubrication is made on passage in view of the speeds obtained after preparation. This preparation requires an additional period of 2 to 15 days depending on our availability! It requires tools and around 4 to 5 hours of work on this cylinder. The price is therefore accordingly.
