I want to know how anyone can say the Arctic Cat Procross chassis and the Yamaha chassis can be any different when it comes to reliability? They are the same exact chassis made in the same factory by the same people. I have the Proclimb chassis and I love it. 850 miles and not a single problem except for some bent running boards(my fault). Its the strongest chassis on the market and wont fold in if you hit a twig like the Doo chassis and its not held together with glue like the Polaris chassis.
You miss read the post bro. We are talking about previous Jap built Yamaha snowmobiles.
I am not an engineer, and I am not a mechanic; If you went on a "per mile" basis, my Pro Cross sleds have actually been more reliable .
You just ride slower?
That’s great you have had that experience, but you are viewing the issue from a limited perspective using only “your” experiences.
I am a mechanic in my spare time and wrench on a lot of sleds and vehicles. Yes anything mechanical will eventually break down, DUH really? Snowmobiles have always been high maintenance, always will be. Over the past 25 years I have seen a lot of machines and I can tell you, the quality has dropped.
Some examples are tiny little bearings in hollow junk boggie wheels, thinner aluminum tunnels, quality bearings replaced with cheap China bearings, poor untested designs that fail prematurely, poor craftsmanship/quality control.
It’s currently the world we live in, disposable everything. Manufacturers have figured out that building high quality, reliable machines puts you out of business and costs more money. Make it look shiny and cool, forget about reliable.
Example; I just went through an M10 suspension, every wheel was in excellent shape, only one bearing was needing replacement. The upper shafts are solid 1.25” aluminum and showed very little wear, 14K miles on the original wheels!!
My Viper has absolute garbage wheels on the entire skid. The bearings in the rear axle wheels are smaller than idler wheels on the M10. Also I’ve broken 3 idler wheel mounts right off the skid, hollow garbage held on with tiny 5mm fasteners, the M10 uses 8mm bolts with a solid aluminum mount.
I’ve bent both the upper and lower cross shafts also. Many have broken the upper shaft and ripped a giant hole in the tunnel.
Anyone who says the reliability on the procross chassis is better than the DB simply has not worked on both extensively. Talk to some old school Yamaha mechanics, see what their answer is.
M2C
This sled has never had one issue, nothing has ever broken on it, just regular maintenance. Do $100 set of rings at 10k miles and your good to go to 20k. Gotta love those red heads!
Oh yea I almost forgot,
it has real paint!
Since when did colored plastic look better than paint?
