The proven Genesis 120 engine finds a new home in the award-winning, lightweight Deltabox II chassis, previously only found on the Apex. All RS Vectors benefit from its comfortable rider-forward handlebar and seat ergonomics. This means a comfortable ride and awesome cornering. Don't forget that the three-cylinder Genesis 120 engine is a reliable, fuel-sipping, high-mileage rider's dream. Both use the easy-adjusting Mono Shock RA rear. Upgrade to the GT 40th's premium GYTR dual-clicker front shocks and 40th Anniversary red and white trim package.
