The updated R6 has improved aerodynamics with inspired styling from the current R1 as well as its 43mm inverted front fork and front brakes, new rear shock, a new aluminum fuel tank, magnesium subframe, ABS brakes, riding modes, and traction control. The new aerodynamics are claimed to reduce drag by 8% over previous models. The engine is unchanged with rear wheel power still at about 100 hp. Body is similar to Moto GP's Current 2005–Present YZR-M1, The 2017 update comes with an OBD port. Unlike previous models, this R6 does not have the same diagnostic mode option. In order to retrieve the diagnostic codes, you must purchase an adapter that plugs into any ODBII scanner. This is the only way other than going to a dealer to erase the error codes.
