M-20 in a viper

[ishpeming fan]

Did it increase your vipers top speed? How much did it cost you for the M20? Do they make Dupont slides for you M20?

Do they make Dupont slides for y

Yes sir!

This is a Yamaha part # for Dupont slides with a Polaris rail profile, which is what the M20 has.

that seems like a better solution than fully clipping the track. Thats a pain in the ars!

Top speed didn’t change much cost was around 2k which is no more than a pair of good shocks and a 4 wheel kit it uses Polaris edge slides I haven’t found DuPonts for it yet but after fully clipping the track I have 2k miles on a set and they look new yet.

Yes they were. Sure was nice never having fear of the rear kicking. I smoked a lot of 5 year newer sleds in the bumps with that setup but hated having to adjust it for conditions all the time. Eventually broke front arm right off when I hit a few big ones on a uphill that I didn't expect and had suspension set real soft. Compromise was setting it stiff and leaving it. Was way to small a sweet spot in that skid without adjusting. Air system and adjusting it I am sure helped broaden the range a lot.

I had a M10 on my 1998 SRX 700s so when I bought the M10 I purchased the skid with the Ohlin shock option. They fixed the narrow performance sweet spot on the M10. What a difference, with the M10 the SRX just swallowed bumps! Perhaps better than my 137” viper with Hygear Axis Pro shocks.

It's my understanding that Team Fast is now offering the M20 in 141" length.
