Engine parts


We have developed and are continiuesly making new parts and testing ideas for high performance engines. In this section you will only find parts that are tested on the racetrack in actual races/qualifying/practices and have passed with flying colors. We believe that only these parts are good enough to offer to You. They are not cheap but they work in extreme conditions.


Aprilia RSV1000 (Rotax V990)



Bigbore piston/cylinder kit 1127cc 13:1. 100% bolt-on, no modifications needed. Kit contains 2 pistons made by CP-Carrillo, 2 steel-lined cylinders, 2 sets of piston-rings/clips, 2 piston-pins, 2 cnc-milled copper headgaskets. The pistons are within 3-5grams of stock pistons so there is no balancing needed. We recomend the use of Loctite 3020 spray when installing the headgaskets as glue.                      


Price is 18995 SEK inc VAT(25%). (Your cylinders in exchange.)
