Power Kit 1000cc 99mm
Plug & Play

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.

TIP – Order Matching Spare Parts and Installation Accessories!

For the proper and complete installation of the Siebenrock Power Kit for BMW 2-valve Boxers, we recommend our high-quality OEM-quality gasket set (Part No. 1100102).

Please note: The gasket set is not included in the kit and must be ordered separately.

A matching piston ring set (Part No. 1125399) is also available separately as a replacement part.

Our Recommendation: Order Silicone Sealant Along with Your Parts!
For reliable sealing when assembling BMW 2-valve Boxer engine components, we recommend our high-quality Silicone Sealant (Part No. 0758376).
Ideal for sealing suitable mating surfaces when installing engine components such as cylinders, cylinder heads and valve covers.
Application Note: Apply only a thin, even layer of silicone sealant to one of the designated sealing surfaces. Always follow the relevant installation instructions.


TIP – Optimized Engine Cooling

To reduce thermal stress on the engine and improve heat dissipation, we recommend installing an additional oil sump spacer ring and/or an oil cooler with all Siebenrock Power Kit conversions for BMW 2-valve Boxers.
