Power Kit Extra 1000cc 99mm
Stainless steel pushrod tubes

Plug & Play kit.

Because of the great demand for optimised kits with almost wear-free nicasil-coated cylinders, there is now also a Power Kit in the Siebenrock programme for those models that were produced before the model year 1980. An adaptation at the cylinder foot of the weel-known Siebenrock parts makes this use possible. The simple installation without modification to the cylinder head is also possible here.

The rider can register a substantial increase in torque and more solid performance for his motorbike with this product. Increase in torque and power over the entire revs range, coupled with extreme spontaneity and solid quiet-running are unbeatable arguments also in this kit for these easily understandable tuning measures.

Top quality.
Small production runs.
Engineered in Germany.
Made in Italy.
