A very large high-end aluminum kit with nykasil treatment, with its 65mm diameter placed on your original 50.68mm stroke crankshaft, this cylinder will offer you no less than 168.17cc. The compression ratio is 13: 1 and the exhaust diagram 194 °.

ATHENA announces no less than 25.5 hp at 10,500 rpm at the wheel outlet on a fully original machine type TDR 125 and no less than 29.6 hp at 11,700 rpm at the wheel outlet on a machine type TZR R YAMAHA with overhead all a torque at 21 nm… enough to make more than a 125 rs drool… Especially since this kit preserves the valve for optimal torque despite the high diagram for power.

We think that the real 37 see 40 hp are largely achievable using an exhaust, carburetion… racing! On request and on the site, we already offer valves, racing exhaust ...

This kit has been really neat, started with a reworked exhaust valve, a cylinder head machined in the mass, completely revised and corrected ducts, a forged graphite piston, its bi segment and its valve will preserve a large torque while let appear very high speeds, more particularly thanks to their hard chrome treatment S10 and their bending. In short, really a must for this type of engine. We will appreciate the degree of finish that athena has applied to this engine. Yet the price is lower than an original cylinder ... According to ATHENA racing, the original crankshaft can amply support this cylinder.

 

This kit is delivered complete with :

Reinforced C-piston clips

High quality forged piston with graphite treatment

2 hard chrome domed segment S10

Reinforced piston pin

Reinforced cylinder head studs

Competition exhaust valve / valve

Machined cylinder head stud

Die-cast aluminum cylinder head cover

Seal and complete screws

We recommend with this minimum kit: 290 jet in the original MIKUNI carburetor , racing exhaust (ARROW, GIANNELLI, TURBOKIT, ATHENA, ...) and BOYESEN valve blades . For those who want more top speed, a +2 tooth pinion is strongly recommended (16 original so go to 18) . Note that a 30 to 34mm carburetor can be used.

 



As an option, we offer a stage 1 preparation, this preparation is a slight modification of the exhaust port by increasing the diagrams. Allow a little extra time for this preparation!
