Just lugging around on one of the Cascade range in Washington's finest lower altitude trails. This is a 2015 crf450r chassis with a 2000 cr500r motor. Engine is TWIRP porting by Millar Race Engineering (MRE) Adam does amazing motor work and really opens the engine up and smooths it out beautifully. The crank was micro-balanced and tin can tig welded by Crank Works Incorporated, and for trail riding I've got a Rekluse z-start pro in here with a full tungsten carbide ball set and matched m5 spring. I added the Panterha Motorsports electric start but modified the stator timing and harness to work with a 2001 cr250r digital ignition. This motor is an absolute beast... it does sign off a touch early now with the FMF fatty and will be getting a Hygee pipe at some point to fix that.
The forks are off a 2013 crf250r (48mm showa) that have been custom valved for aggressive single track and dessert riding. Rear KYB shock I did a lot of valving work on, as well added the SDI clevis with rebound adjuster to widen the range of adjustability.
almost too much chassis mods to list, but the twisted engineering carbon flex bars are an absolute game changer with a bike that vibrates like this old 500. Matched with XCGear spurs polymer isolated foot pegs this setup really keeps the numb feet and hands from happening that these bikes are so well know for. I was actually surprised the aluminum frame had less vibrations that the old steel one as well.
Fun bike, lots more to come on this bike in the future.
