KTM 250SX conversion

I am finally getting serious about the dual purpose conversion of my 2020 2 stroke motocross KTM 250.

I am converting this into a light and agile single track bike. It was set up really stiff for MX racing. I already softened the suspension, retuned the powervalve and carb for a more linear power and, comfortable midrange and low end performance.

Now I added a keyed ignition switch, patched it into the kill switch circuit (off position). In the on position, it powers the DRL, turn signals, brake lights, horn, and a headlight relay.

I got a Polisport headlight with excellent colormatch, orange/white. It has DRL, and I replaced the Halogen bulb with an led high/lo bulb. I found a turn signal/Hi/Lo beam, horn button control set, included in a kit with horn, adjustable delay turn signal flasher. I added the SPST switch by the mirror mount to turn on the headlight relay. I have sequential front turn signals (led), not mounted yet.

The teeny button rear turn signals have running lights, brake lights too.

I did add a Warp 9 adjustable kickstand, rear shock lowering link (about 1 inch), and dropped the front forks to lowest position (maybe a half inch). OK, so the kickstand adds a pound or 2. Gotta have a kickstand!

It's a work in progress, but I need to get this out of the garage to help my son build his new Templar X in a week or so
