One of the annoying things about my 2017 Vee is the very clunky gear change, especially 1st to 2nd. I read somewhere that this was due, in part, to a 2mm misalignment between the front and rear sprokets. Something the engineers at Suzuki seem to over look every time they up grade the Strom.
So I invested in one of CyMarc's gear enhancer. basically a 2mm spacer that fits between th rear sprocket and the hub. Nicely made bit of kit. Whilst fitting it I was a bit sceptical. But the differance is amazing. Changing gear is so much smoother.
Well worth the money, as smoother changes has got to help preserve the gearbox.
