I haven't heard much about them, but I bet they are the best stock shocks of any production ATV. They may not be as good as PEPs, Elkas, ... but i bet they will work awesome for the majority of us. Seems like yamaha really paid attention to what the high performance riders wanted. I think it's great that they are rebuildable and have all that adjustability.
I don't know if this is legit or not, but some guy at Cannondaleriders.com claims to have ridden the YFZ. He said it's almost on par with the Moto in terms of power, and the handling is excellent. He also stated that the suspension is a little stiff for trail riding, but it would work well on a MX track. Sounds good to me!!
Nic Grandlund is one of the guys that got to test them this week. A glowing review from a HARDCOR racer is always a good thing. And he says that with a pipe, filter and re-jet it will hang with his moto on the track.
these are Kayaba Fronts i believe? this is the same company that builds a lot of the dirtbike front forks and rear shocks and there are a lot of bikes right off the showroom floor so if they used one of these companies then i have no doubt in my mind that this is an out of the crate RACER !!
Kayaba makes most of Yamaha's shocks, including the dirtbikes and ATV's.
Showa makes most (if not all) of Honda's shocks.
These 2 companies probably have more field time with testing on works type bikes, custom one off's, and an endless budget than any 2 shock maker's combined.
If you think about it....Kayaba makes all of Team Yamaha's custom shocks for their racers in the Supercross series, and the MX series. Plus all of Yamaha's trikes and quads back to date. (from what I know)
Showa makes all of team Hondas shocks (like Ricky Carmichael's 25,000.00 dollar rear Supercross shock) plus they've probably had more works quads (the honda Rincon that won the 2002 Baja 1000.....) and trikes (they used to be HUGE into trike racing) than anyone.
I would rather have a custom set of shocks from these guys than any aftermarket company out there, to bad no one could afford a custom set.
My dealer wont even come off of freight and setup and I AM BUYING 2. So instead I jewed them out of 35% off of all the parts I buy from them til the end of the year :lol
P.S. I am willing to bet that Wayne at PEP already has a set of these shocks in front of him and he is working them up as we speak.
Independent aluminum upper A-arm front suspension features fully adjustable competition-spec Kayaba piggyback shocks with 9.1" of travel and separate adjusters for preload, rebound and compression damping.
Rear suspension system is a YZ linkage-type that features fully adjustable Showa shock with 10.1" of travel and separate adjusters for preload, rebound and compression damping
