gearing

Looking for insight: I have a 2006 RS Vector been out on a few rides this season all is good. However my top speed is 72 mph. The acceleration is crazy fast, I can get to top speed like crazy but it’s just not going faster. The best I can tell I’m reaching top speed around 8k rpm. No other...

Hi guys on my 07 Apex mountain I have a 23T top gear, and I think stock bottom 40T gear on it. I want to add reverse to this sled, so am going to buy a good use complete chaincase from a Apex gt. Now I know the gearing is going to be off. My question is I want to set up the new chaincase to have...

Hi guys, so I have a 2007 Apex mtx I bought with no reverse. I am wanting to add reverse to it. So I can get the whole complete chaincase with reverse for around $340.

Hi, Just bought a used 2009 Nytro MTX 153 for a backcountry hut access machine. I want to take the kids on it, tow a skimmer and be able to get up into the mountains on logging roads. Cost, durability and reliabilty are all musts, which is why I went with a yammy. Can you give me advice on...

Hi everyone, after installing my mpi 180 trail kit on my ltxse, a little clutch work, primary is machined for overdrive, I hit 109 on my gps. I would like to go a little faster on the lakes and maybe get better fuel mileage on the trail. I'm down to 10 or 11 mpg now. 120 mph should be good, so I...

i have a 2014 viper xtx with stock gearing. I know that many people change gearing to achieve higher top speed. For me, 85 or 90 is plenty but the acceleration is what I'm interested in. Would gearing it "down" give me better acceleration? If so, does anyone have a suggestion of what...

We have developed an all in one speed upgrade for your MPI 190 turbo SR Vipers. This kit includes a new lower gear, hyvo chain, machined helix with overdrive acceptance, secondary spring (set at 3-3), and secondary washers. We have seen drastic improvements over stock gearing/clutching as this...

I have currently a phazer fx but gonna extend it to 151 becouse I realized that the fun is in the deep snow.. but I would like to have the power at low speeds becouse I honestly never drive faster than 90kph... I read that gearing it down will just do that the clutch bottoms? If you gear it to...
