you can put electric on the 670z. my mom had a 98 with both electric and reverse. girlfriends mom just got a 99 and it came with both as well. in 99 it came with it and was called the formula deluxe I think. thats what girls moms sled is called I think. so anyone else have trouble with the rear suspension riding real rough on less than perfect trails? hers was so bad she traded it after a year and a half.. we ussually trade when the sleds are real old and lots o miles

my 97 600 sx had 9000+ miles

we tried to tune it but dealer didnt know what to do since it was a new skid. always wondered if we were crazy or not. seemed like a nice sled other than that problem. real grunty on the low end

think snow guys
