Description Fitment
Finally a 60cc piston kit for the 2009-2019 KTM 50’s Nihilo Concepts teamed up with Wiseco the leader in Piston manufacturing to develop the KTM 60cc kit. Up until now there was no way to easily turn your 2009-2019 KTM 50 into a 60cc big bore. We all remember the 60cc kits for the old style motor but they didn’t work in the 2009 and newer motors. It was possible to do the conversion but that involved splitting the cases and doing case modifications. The new Nihilo / Wiseco piston kit is sized perfectly and will fit right in without cutting the cases. You will need to bore and re-chrome your cylinder to the new 43.5mm size but once that's done it’s a simple matter of installing the new top end kit like you would a stock piston. The kit uses the stock wrist pin bearing and comes complete with Piston, Ring, Clips and Wrist Pin. We are still testing with some fast Mini riders and will have carburetor jetting specs and other tuning recommendations soon.

You can send us your core and we will bore and re-chrome it for you plus we can supply any other parts you will need to turn your 50 into a fire breathing 60cc Monster.

You can also purchase the entire 60cc kit here as well. Just choose "Complete 60cc Kit" in the drop down option, and a representative will contact you after your order is placed.
