Description

This kit is for bikes that are already 1000cc 1977-1980, to be used with 1000cc cylinders heads.

Enjoy the benefits of Nikasil cylinders on your 77-80 R100 which BMW used as original equipment beginning in 1981.

No cylinder wear, better compression and improved oil control. The Nikasil plating is applied directly to the aluminum cylinder with no steel barrier resulting in significantly improved heat dissipation and lower combustion chamber temperatures. This means longer engine life.

Dual plug ignition is recommended due to high compression pistons. You can install low compression base gaskets (part number 11111335650) to reduce compression to 8.8:1 to eliminate the possibility of damaging pre-ignition, otherwise known as pinging.

Kit includes:

New Nikasil cylinders.

Stainless steel pushrod tubes already installed.

Lightweight 1000cc 9.5:1 pistons.

Pins, rings and circlips.

Kit is complete except for top end gaskets which you can purchase below.

You would use this kit to replace the old steel liner cylinders used from 1977-1980 that were prone to wear prematurely and were not very stable when bored first oversize. We do not recommend boring R100 cylinders.
