I road
I road the madrussians xtx for about 100 miles one day. I happened to own a 2012 Procross at the tine. There was no comparison the cat "current viper" was head and shoulders better. It was close in weight but felt like a much lighter sled. My biggest issue with the Cat was it broke every time we road and blew a belt every 400 miles.
The seating position on the apex is very old school. I feel like I'm slouching when I ride it. If they made it more rider forward and lowered the motor like it is in the vector I would like an apex. Have you ever road a vector? It feels much lighter then an apex.
Anyone who says the weight doesn't matter hasn't ridden a Viper. The Viper should have a much lighter feel compared to the Apex, My Cat did. I just can't ride a cat again and that's what the viper is. Also performance wise the viper is underwhelming. We race on anchor bay every weekend we aren't on the trail. Last weekend The Russian and I both raced a turbo viper 10 or 15 times and smoked it every time.
Again I really want to ride a Yamaha. It just hard to justify riding one when none of them co pair to what I ride now. I'm crossing my fingers that 2017 brings a new apex maybe named SRX
