An exhaust for the M1 was among the new components Yamaha brought to the Misano tests. Yesterday both Valentino Rossi and Maverick Vinales talked about it (without much enthusiasm to tell the truth) but they hadn’t seen it yet as the pit lane was closed to both journalists and photographers.
In the photo above you can see it mounted on Maverick’s bike.
This is a dual exhaust, similar to that found on the Suzuki GSX-RR (also with in-line 4-cylinder engine) introduced this season.
The new component makes the M1 more aggressive, but in MotoGP aesthetics don’t mean much. Rossi and Vinales need to see if it improves the performance of their Yamahas and if it does we’ll be able to see it in the race too.
