I've got a 2003 RX-1 for sale with some interesting mods that it's time for me to let go. I've owned this sled since about 2005 but have put very few miles on it the past few years and need to free up some space. This thing rips hard for an "old" RX-1. On a decent hardpack trail will show you well into the 120s on the speedometer with ease. Only real issue is the hood is scratched up from an incident inside a trailer, but it is ready to ride. Currently 13,100 miles but rebuild was done at 10,800 miles detailed below. Brand new battery this year. $2500 located in Mid-Michigan. PM or email butterfield.doug@gmail.com

Engine:
Ported head
Apex valve springs
Slotted cam gears (timed to like 10,800 rpm)
Raised compression (thin head gasket)
ECP filters w/ Holtzman CV springs
Advanced ign timing (still runs on pump 93)
Engine work along with new pistons / rings / bearings was done at 10,800 miles so there is about 2,300 miles on the build

Clutching:
Heavy Hitters in primary
Team Rapid Reaction roller secondary

Chassis / Suspension:
136 Monoshock Skid
1-3/8" Cobra Track (great condition)
Newer skis
Apex Seat
Apex Handlebars / riser
