Joint ATHENA (one of the best seal manufacturer in the world), we are clearly on the very top of the range.

The increase of the cubic capacity, of the compression as well as the reduction of the friction, the temperature in the room will offer more performances to your machine! It's Monstrous! Here, it is not only the maximum power gain that is sought after! The power comes sooner, faster, and a good increase in torque is present! It's all that makes a kit very robust and powerful. Mounts with the original cylinder head without modification of the latter.

 

Delivered 100% complete as in the photo, with its 2 cylinders, the two pistons with segments, clips and axes, the complete pack attached but also the big cullasse overcompréssée with its two studs!

 

Already in normal times, this quad is a fun machine, be careful because with this high performance kit it will not be available in all hands. We have all the spare parts for this product. We have a power of 50.89ch with this monster! For even more perfs, we recommend pairing it with the TK exhaust below!

 

Optionally we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the bottom of skirt is also included in this modification. Allow a little extra time for this preparation !
