NEW 500cc 2 Stroke Motocross Prototypes

Discover my new 500cc 2 stroke motocross prototype bikes. I installed this time a Honda CR500cc engine on a 2017 CRF250 frame and managed to create also a dual muffler. Then I took another old CR500cc engine and placed it on a Suzuki RMZ frame for a supercross rider. Listen these beasts roar and long life to 500cc 2 stroke bikes
