Thanks. Considered a 42 as well but didn't want to chance the sensor fault...decided to change the rear to keep the rubber dampened original front sprocket. So I'm guessing you've been able to drop your revs by a 1000 or so at 100 kph? Must be nice on the highways.
BTW, had a V-Strom 650 for several years...great all round bike, and perfect for 2-up...like a fool, sold it when I didn't ride much for a couple of seasons. The Versys X-300 is somewhat similar, but feels like a super lite version (probably 45 kg less), even though it feels taller and almost as big. Wonder which of the two you ride more.
