Hey all, not new here and neither is this bike. It has just been evolving. I'll give a brief back story and ill start the build in subsequent posts.
2011 KTM 450 SXF. I bought this sight unseen from a dealer about 4hrs away in North Carolina. This was supposed to be my built supermoto race bike to replace my 2012 450. The dealer kept telling me it was "all stock, low hours, clean". I knew it wasn't from the pics but took the gamble as it was a good deal for the time. Turned out when I got the title it belonged to a dealer in Texas of which I knew the owner. The bike had raced a few pro MX rounds in 2011 but was sold off after the season. It basically sat for 4 years and changed hands a few times before I got it.
When I got it in 2015 I got about 1hr on it before it stopped working. Inspecting the airbox and wiring it appeared to have had a fire at one point. It has an open air cage with no backfire screen so im guessing that did it. Also the starter lead was suspect. The reason it stopped on me though was a tight link in the cam chain and possibly oiling issues. It ruined the journals on a cam and messed up the head. When i sent the head off to be repaired the freeplay in the crank was border line so i just rebuilt the whole motor. This was 2015 ish. Now it has a fresh motor. 13:1 compression. Head was welded and line bored. Valve job. new bearings, new rod installed by KTM on my crank. and on and on. I put a high flow water pump on it as well as a Trail Tech 90w stator/flywheel weight.
I rode the bike off road a little as well as at the supermoto track. Seemed to have issues every time. Once the coil went bad. Another time the starter gear one way bearing got really loud and turned out the cage had come apart. At the SM track the muffler melted the mounts. Fingers crossed it's all sorted now and no more bad luck!
Since I had the title I took it as well as my bill of sale for my 2012(before i sold it) and went to the dmv to try and title them both. This bike I was able to street title without issue, not so lucky on the 12. Now that It has a street title I thought I would complete a long time goal of having a street legal dirt bike......
