Not homologated on open road, formally reserved for competition.
The maxi TPR kit is the kit par excellence from Top performances, it is made of top-of-the-range aluminum with a 50mm bore and a full-mass crankshaft with a reinforced 44mm stroke, over-balanced via 4 masses, it develops 86cc of real full power. Admittedly more expensive than the cast iron maxi kit but nothing to do, we have here a real brute with enormous diagrams (190° with the very wide exhaust which is with bar), forged piston mono segment end reinforced domed...
The 44mm stroke crankshaft will give you a lot of torque and the d.50 thermal group with bar will also give you a lot of high revs... Which makes this kit a weapon of torque and power. We recommend it for competitions, prototypes, drags, preparers, namely that this kit does not have the same solidity or longevity as cast iron, here it is really the power that is sought. TPR has of course equipped this kit with reinforced bearings, one of which is made of thick silk included in the pack and a studded cylinder head to better extract the heat. This kit takes a lot of turns and is strongly recommended with an internal rotor ignition. We appreciated the degree of finish, the accessories provided such as the special ignition shift key...

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!
