Kit 185cc MALOSSI Ø63mm, cylinder / piston + electronic housing for YAMAHA WR R, X and YAMAHA YZF-R 125

Attention, unauthorized part on open road, reserved for competition on circuit, does not respect the 125cc displacement!

High quality, MALOSSI whose quality is no longer to prove that shares its design and the use of high-end materials! Thanks to its diameter of 63mm and its displacement of 182,58cc real. A very torque and robust kit!



This competition kit will offer you big performances! Delivered 100% complete as presented. The cylinder is made of aluminum, the piston is extra compact with three segments but also lightened and reinforced with enlarged heat exchange surfaces, the segments are special for optimal resistances, in other words to increase the power radically in complete serenity with Quality equipment.



Do not hesitate to download the official PDF from MALOSSI explaining from A to Z everything you need to know about this kit, the electronic case and more!

This kit is the same as the kit delivered with the electronic box, which takes the injection cartography to make the necessary modifications, the gain is therefore higher than with a kit without case! In short, it is a very powerful and coupled kit, but also extremely reliable! Our customers are able to make more than 25 000km with these kits!
