Truly a remarkable riding machine. I am a seasoned pilot, supersport racer, boater and ultimate thrill seeker and at times it can be a real challenge to recreate the adrenaline rush we’ve all experienced on our first barrel roll or hair pin. The R15C is the only bike on the market that can consistently satisfy the desire for thrill and adventure. Every aspect of the R15C is developed with the highest standard of craftsmanship only obtainable by trial and error over decades of focus and determination. Bravo Jim Turner and the Optibike team, thank you.
