SideWinder Gearing, Tracks and Drivers

[snowbeast]

I was told chain is 15 wide hyvo. The dyno reports showed a peak of 204.1 hp @ 8850. Spinning at 8850 will get you 121.42 mph using .91 for overdrive, that is 2.86 pitch and 9t drivers.......Yamaha said these clutches are designed to pull a bit of overdrive so I think it's safe to say an LTX is geared for 121.42 using overdrive. 9000rpm equals 123.48 mph according to charts with .91 overdrive

That's correct,and this is why so far all the testers who held it wo found speeds in the 122-123mph on the air strip and dimmerman and his buddy racing on a lake going 1/2 mile stretch saw 122-124 speeds and the old style zuk 9000 twin was huffing and puffing to see 115-117 and it was clearly tapped out in stock form,but the 998 was just out of gear,but said had plenty of power left to run much faster if geared. Oh ya,also said there 998 was pulling 9000 rpms as the overev sometimes will give you a couple more mph.

I have the XTX LE 137 with the 1.75" back country, does it have 9T drivers and 21/41 gearing as well?

I just received this info from Yamaha on the gearing of the SideWinder Models.

Track Lengths: 129 – 137 = 9T Drivers x 2.86 Pitch & 21/41 Gearing

Track Lengths: 141 x 1.6 & 153 X 1.75= 8T Drivers x 3.00 Pitch & 21/41 Gearing

Track Lengths: 141 X 2.25 & 153 x 2.25= 8T Drivers x 3.00 Pitch & 24/50 Gearing

Track Lengths: 162 X 3.00 = 7T Drivers x 3.00 Pitch & 21/49 Gearing

So what would top speed of 141x1.6 be?

Anyone know the gearing on the new 2018 mtx with 8t drivers?

I know this is old but. Top gear 21 bottom 53. I’m trying to add a little speed to mine and info is hard to find on these mountain sleds
