Client Testimonials

“it’s been amazing and performs exceptionally well for its price. Unlike spending $4,000 to $6,000 on a Sur Ron, the X21 offers great versatility and can be ridden like a regular bike on the road. I nearly bought a Sur Ron, and I might still get one because I love dirt bikes, having grown up riding them.”
“I was a little apprehensive due to the lack of reviews here stateside but the price couldn't be beat and the second I was told that the warehouse was in Cali I pulled the trigger. By far one of the best sub $1900 investments I've made.”
