A very good kit at low prices whose reputation is second to none, this kit is very renowned for its performance, its solidity and its more than reasonable price, with a diameter of 47 millimeters, fairly advanced diagrams. The kit is very clean and finished as usual for Top performance kits.
We recommend it to those who want something to ride every day (Outside France) and those who stunt because this kit is really torquey and solid thanks to its MINACROM treated cast iron. Its color is quite sober with its semi-shiny black.
We can make him reach even more power thanks to a preparation. Supplied with reinforced clutch springs because the power developed is too high and causes the clutch to slip. This kit also has a reinforced high compression cylinder head.
The pack contains:
-X4 reinforced clutch springs
- a d.47 mm bi-segment piston
- original diameter piston pin
- 2 piston clips type G
- reinforced full seal pocket
- high compression cylinder head
- chrome cast iron cylinder 5 normal exhaust transfers
- 2 reinforced segments including a domed polished hard chrome
- instructions in French
We advise to mount at least to accompany this kit:
Air box inflation/carburetion 17.5mm/reinforced bearings/cold competition spark plug/adjustment/racing exhaust
As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement of the piston and the lower skirts is also included in this modification. Count a little extra time for this preparation!
