Power Kit Extra, 1981->

This upgrade kit provides everything the enthusiast needs to upgrade their R80 to 1000cc capacity, model years 1981 onwards. The kit includes two nicasil-coated cylinders, two forged lightweight pistons along with the required wrist pins, circlips and a full set of piston rings. The Extra kit also includes stainless steel push-rod tubes pre-installed in each cylinder. Installation of this upgrade kit will enable a power increase of approximately 10hp to 59 hp - as well as an increase in torque - and you should notice smoother running due to the lighter and carefully balanced pistons.
