The Motosport Alloys M12 Diesel is the first UTV and ATV compatible wheel to feature the MSA bolt-on cap for clean looks that are as sleek as it gets. The great looks of the M12 are available in two finishes, a gloss black and brilliant chrome, neither of which will leave you starving for attention. The M12 is more than just looks though. The construction consists of a lightweight aluminum alloy that has a remarkably low porosity for high strength and a high luster when machined. And like all MSA wheels, the M12 Diesel comes with a Lifetime Structural Warranty from the manufacturer to ensure the M12s will have a home on your machine for many seasons to come.
Available in deep gloss black automotive grade paint or a durable, brilliant chrome
Made with lightweight aluminum alloy used in low pressure casting for high luster and low porosity
All Motosport Alloys wheels (excluding beadlocks) come with a Lifetime structural warranty
Cleaned up easily after getting muddy, worked well and looked good.
MAKE SURE you order long lug nuts with these as the machined holes are not large enough for a 17 mm thin wall socket I purchased lug nuts Ruth a 14 mm head and moose long lu nuts to facilitate mounting.
These rims look amazing. I haven't had the chance to instal them in to my atv but I'm sure they will be fine. I am interested to see how well they hold up. Everyone else had good reviews for the most part, I will update as soon as possible.
The wheels are very nice and appear to be very well made but Rocky Mountain ATV/MC failed to mention that you must use Motosport Alloys Lug Nut Kit in order to mount these. TECH NOTE: WE NOW MSA LUG NUTS FOR THESE WHEELS.

I have had these wheels on my machine for 18 months now and they are very strong the finish is second to none they do have a few scraps and scratches but that is to be expected with over 2000 miles of riding in areas such as Hatfield McCoy trails in WV and Taylor Park CO. You do need the Moto Sport alloys lug nuts to mount this wheel to the machine no others will work and a thin wall socket. the quality of these wheels is top notch you will not be disappointed in your purchase and the look great to.

I learned the hard way on this wheel... the lug nuts are recessed COMPLETELY into the wheel holes.
You'll specifically need part #1087210004 to mount these to a Can-Am Outlander or Renegade (2012 or earlier). They need to be tapered, and you'll need a thin-wall socket to tighten these down.
When I ordered these, they were still a relatively new wheel to Rocky Mountain, so they didn't have much experience with them. Their excellent support staff was very kind to help me figure out what I needed.
Rocky Mountain gets an A+++ for service. M12 Wheels... gets a "fair" rating. To be honest, the finish and look is great, but mounting them up has been a nightmare. In the future, I'd go back to a style like ITP SS wheels I had on my last Renegade. No problems mounting those up!
