- Yamaha’s M1 is known for its relative mechanical simplicity. The shock absorber can easily be swapped out in just a few minutes which helps maximize set-up time during MotoGP’s timed Free Practice sessions.
- The M1 employs an pair of 320mm diameter carbon fiber front brake rotors and Brembo’s latest monobloc-style four-piston calipers. Compared to metal discs the carbon fiber set-up requires significantly higher temperatures for optimum operation.
- The cockpit of Jorge Lorenzo’s racebike offers a multitude of adjustments in terms of electronics and chassis. Interestingly the new YZF-R1 production bike features many of the same styling elements as well as electronic strategies employed on the ’12 M1.
- Yamaha claims its factory YZR-M1 weights just 348 pounds. That’s a whopping 91 pounds lighter than its all-new 2015 YZF-R1 liter-bike.
- While both Valentino Rossi and Jorge Lorenzo’s factory M1s use Akrapovic exhausts, Valentino’s bike (pictured) features an different, more open looking exhaust tip/muffler set-up.
- The YZR-M1 is known for its high-level of adjustability. The position of the swingarm is finely adjustable. Like other MotoGP bikes the M1 employs an dry, racing-style clutch which reduces parasitic power loses compared to a production motorcycle’s ‘wet’ bathed-in-oil clutch.
