I've heard more often than not that the Grizzly is faster, but I seriously doubt its a big difference between the two.

I have a Grizzly, but I would prefer the Rincon's transmission to any bet drive. I think that the Rincon tranny takes away from it though being a 3 speed. They should have put the Rubicon transmission in it in my opinion. No qualms about that one.

 

the grizzley its the fastest in dirtwheels it said the top speed was faster than the P650 and the rincon

 

The speed difference is not much, and also quite trivial. If I were you I would go for reliablility, in my opinion I would go with the Honda.
But thats my opinion.

 

"the grizzley its the fastest in dirtwheels "

Yamaha also has the most full page ads in dirtwheels. My bro has an 03Griz and I have an 03 Rincon, if I get stuck he'll pull me out, if he gets stuck i'll pull him out (at least i hope he will, so far it has only been me pulling him out). Not real sure who has the fastest machine, but they both seem pretty close.
