  • Sled:2005 MXZ X 800 HO

Posted 11 April 2019 - 07:11 PM

I have a 2005 MXZ X 800 HO. Extended 121” to 144”. Went from the 10 tooth drivers to the 9 tooth drivers. Track is 144”x 15”x 2”. Gearing is stock (25 top, 45 bottom). Weight plus gear is roughly 220 LBS. I ride on the trails probably 75% of the time. Just wondering what gearing you suggest with an I backshift kit. Thank you for your time. Any help would be appreciated.

Hello Andrew.

05 stock 121 25-45 gears for a maximum overdrive speed of 127mph.  The only way a sled with a summit track like yours will go that fast is if you put it in the back of a truck or fall off a cliff.

 

A modern 146 x 2.0 has 23-51 gears for a maximum overdrive speed of 93mph

 

With your sled then can go 20-45 for a maximum speed of 91mph.

 

Thanks

joey
