Belt drive choices

Summit74 · Sep 27, 2017

TKI - has one $799
MVM - has one $850
Anyone else C3? Or they out of business??

Few pictures of what I have found. Looks like Brett Rasmussen is using the Mountain Valley Machine, TKI has a great reputation and proven. What are the differences besides price? Both include a belt for the price.

Anyone in the know?

Belt drive

Spend your money on hp & weight savings elsewhere. Maintenance on a chain case and a new chain every year saves a lot of headaches in the hills. Been thar for 2 full seasons never again. Lots of promises & guarantees lots of money & broken belts. Lots of calling transmission shops crossing belt part#'s out of town on snowmobile trips.

Above post is totally correct.. Went threw more belts over the years than one could imagine, then when I called manufacture and gave him specs and application, he said it needed a much bigger belt, some guys have good luck but then it might say what hp there making as well

You can definitely spend that $800 better elsewhere. Especially since there is very little weight loss with a belt drive in an 850.

Bought a TKI this year, yes I know some say gains and others say waste of money. But for me Im just tired of messing with chaincase oil so just for that it was worth it for me.:face-icon-small-hap

What if you have an abundance of money and are just looking for things to buy for your sled until it snows? :face-icon-small-dis

I've not heard of the stock chain drive being problematic on the 850.... and any belt drive efficiency improvements, if any exist , are arguable at best and have been covered ad nauseum on the fourms.

Ran a TKI on my xm summit X. Never had one issue. Zero maintenance after break-in. If it did blow you can change it on the mountain and it won't damage other parts. No oil to change. If you have the extra cash, do it. I have read and seen turbo guys running belts with zero issues also. Easy to play with gearing also.

https://c3powersports.com/, depending where you live C3 is in Canada (BC and Edmonton?) and that would make a big difference in cost for some purchasers depending on which side of the exchange rate you are.

I have never owned a belt drive and don't plan on buying one but I have ridden with several folks who had a C3 on earlier sled models and no problems at all with proper belt tension etc.

I have seen one chain case broken on a stock 146" that wheelied everywhere he went and jumped constantly. I never saw him check the chain tension???

I bought a TKI for my G4 simply for the ability to replace the belt on the mountain instead of wasting an entire day hauling a busted chain or gear. Wasted a premo day last year hauling out my AXYS with a busted chaincase and told myself I won't ever do that again if I can help it! And with the extra long chain of the doo I know there will be some advantage with the belt drive in efficiency.

Update: Been researching the the Mountain Valley Machine belt drive more. I had a great phone call with Dave from MVM and owner Todd Williams via FB chat. Here is what I have learned. Before you go off say just buy TKI, I think the competition deserves a good look. So differences that I have discovered are, the MVM has a tensioner that is built in to the all aluminum block that bolts to the case, tension is locked down by 2 bolts vs 1, no plastic anywhere in the cover, it uses a 36mm wide mitsuboshi belt, 63 or 64 bottom gear, choice of top gear. The cover in the pictures is NOT the final cover, that is a prototype cover. Todd said he will send me a picture of the final cover, all aluminum, by Tuesday or so. These will go into production in next week or 2.

MVM has been making drives for Arctic Cat and ski-doo for couple years now. They also have a drive for T3 sled owners. This is not a first go type of thing.

Tensioner in the cover= bad idea.

TKI uses the stock tensioner and hard anodizes there sprockets.

Sorry I should not have said it's in the cover. Both the TKI and the MVM use a similar tensioner. The TKI is locked down via 1 bolt and MVM 2 bolts. Tension looks to be adjusted differently though. See picture below of the TKI tensioner block. I don't see where TKI uses the stock Gen4 tensioner. I know it did for the T3, but that may have changed w/ this new chaincase design

PaulAnd · Oct 4, 2017

The stock 850 chaincase is the main support for the front of the running boards where you would stand... so I think stock inner and outer covers work together for strength/support.
I only see 4 small 8mm
Bolts and 4” of tensioner bracket providing support for tensioner and running boards

The TKI uses the stock tensioner system. The part you circled is just a guide for the idler to slide and lock onto. Same as the xm kit.

Yes I see what you are saying. the stock tensioner on the Gen4 has been unreliable for some guys vs the XM, so hopefully TKI using that system will be reliable since the idler is locked down anyway.

Save your money!

Based on my personal experience a belt drive is not worth the money.
