no

I said the same thing for 10 years

Anything is possible. The problem is the thickness of the cases. You'd have to make each gear a little thinner to fit a 6 speed into the width of a 5 speed. Could be done, but would be expensive and time consuming.

Is it still faster off the showroom floor over a renegade 1000... top speed wise???

Didn't do much for the 250r still the same final ratio as the 85 to 86 5 speeds. Just have to shift more

I assumed they added a sixth gear to the 250, keeping the final ratio the same, to give the rider more ratio options to keep the engine in the power through varied track conditions.  That might explain why the 250, with less torque, would get an extra gear while the 500 would not since it can pull the higher ratios and be less sensitive to larger steps between gears.

Nopick nailed it............

No really good reason it needs a 6th gear.

I'm not mining for old posts, just signed up..........the can-am 1000 atvs are limited to 77mph by the factory. My bro has one as well my cousin.
