Power Kit 860cc R65
Late version: After 09/80 production
We have always been a big fan of the R65 models! The short stroke gives the bike a completely different character compared to its larger displacement siblings. All of the outstanding attributes of the R65 are retained with this kit but a substantial power and torque increase really transform the performance an fun factor.
The Siebenrock kit increases the displacement from 650cc to 860cc and this equates to 22% increase in power from 50 to 61 HP and a 59% torque increase from 49 Nm at 5500 rpm / min to 78 Nm at 5080 rpm / min. This amazing result means that you will have noticeably more power and torque at a lower RPM, so you no longer need to wring the motor out to make it go.
The very complete kit consists of the following :
- Nikasil Cylinder Set
- Matched Piston set
- Stainless Steel pushrod tubes
- Wrist pins and clips
- Top end gasket set
- R65 models 1981 and later
