Well, this is overdue. If I’m honest, I was pretty busy trying to get this whole thing together…
First the backstory:
I have been riding the same 2008 KTM 525 XC since I bought it new in March of 2008. It has been a great bike and by the end of 2014, had over 310 hours on the hour meter that I installed the day I brought it home. Unfortunately, time (and 6 years of GNCC racing on the same bike) has a way of getting to things, and most of the bike has been replaced over the years. This meant that every piece of it was a different age and it seemed like I was wearing out something different every race.
Eventually, I decided that I really needed to re-zero the hour meter. But that meant buying a new bike which KTM didn’t make. I did some math and came to a conclusion a lot of folks may find surprising. With my spare parts inventory and the sponsor relationships I have developed over the years, it was much more cost-effective to BUILD a new KTM from scratch than it would have been to do a whole-sale brand change. Especially when you consider that this approach would still leave me with 2 other fully built bikes for backup / practice purposes. Not to mention, I still wholeheartedly believe that this is the best bike our industry ever produced for XC racing.
So, in September of 2014, I bought a new frame and subframe and started laying out a plan and gathering parts. My goal was to build a KTM race quad that would be worthy of the Factory team if it still existed, complete with updated graphics to mimic the look of the current KTM factory race teams. Finally, last Thursday 3/5/2015, I finished it and loaded it and the backup bike up to head to the FL GNCC!
The finished product is all new except for the engine (which I had built from new parts only 16 hours before), the HiPer Wheels, the shocks, the carburetor (which is a low hour FCR MX41), and the Precision Dampener. By the end, leaning heavily on my amazing sponsors I was into the project for significantly less than the MSRP of a 2014 450 sport ATV!
The battery side of my wiring harness. I have a rough time giving someone money for something I think I could do better anyway. Rather than buy an OEM harness and race-gut it, I bought connectors, several crimping tools, and 14 colors of 18ga TXL crosslinked automotive primary wire and built a harness right the first time!
The rectifier side of my wiring harness. This actually runs the bike without the battery side even connected. Meaning even if I lose the key switch, a battery connector, or anything else on the battery side, I can still kick-start the quad and get it running!
