2021 Triumph Bobber Updates Increased tank capacity from 2.4 gallons(9.1L) to 3.2 gallons (12L). Euro 5 compliant for cleaner emissions and better fuel efficiency. Reduced engine inertia improves throttle response across the torque curve.  The Front tire is reduced from 19 inches to 16 inches. This permits a thicker and wider tire to help with suspension and create a larger footprint on the road.  The Fork diameter increased from 41 mm KYB to 47 mm Showa cartridge forks.  Brembo 2-piston, twin disc and sliding calipers ensure greater stopping power.  The Rake is reduced by 0.4 degrees in conjunction with the reduced front tire size to improve turning.  A Brighter LED bulb replaces the traditional halogen bulb.  The Single clock gets updated styling. 3 new colors were made available: Matt Storm Gray, Matt Ironstone, and Cordovan Red.
