So, I pulled my head to do the titanium valve retainers, and found this Found my coolant consumption issue. Crazy, because not a single BHG symptom. No overheating, no oil in water. Just a CEL after I installed the rapid bike, and a lot of liquid in my crank case vent. Glad I pulled this...

If you guys clean and lubricate your chain a lot, make sureyou remove the front chain guard every so often and clean behind there as well.I took mine off a couple weeks ago and it was pretty dirty behind the guard andI always thought I kept my bike very clean. Now that I know better, I’ll...

...as in riding off into the sunset, so to speak. Haven't been that active on the board in the last more than a little while. Unfortunately that corresponded to the RC spending more time idle than it deserved. With that as a premise, the little beast is headed to a new home. I was apparently...

Took a lot of haggle but got it 5k and some change OTD

So looking at my bike today with the fairings off, an 18, I noticed that there is a loom that goes into the nose piece that comes down the right side of the bike to 2 connectors. I'm keeping my bike street legal but it will see a lot of track time. I'm thinking I need to figure out which wires...

Hi, Just got the 2017 RC390, in hopes to build it into a track bike. Hope to receive a lot of help from the forum :)

Just curious to hear from guys who track their RC390's... is a steering stabilizer necessary on these bikes? I'm sure it depends on track and how hard you are riding, but it seems a lot of the cup bikes don't have them so I assume they are probably not as important as on a bigger bike?

I bought my 2016 RC a few weeks ago and picked it up yesterday. A quick background on me, I have been riding street motorcycles since 1978 and have owned many. Unlike many guys my age I prefer sport bikes and was intrigued by the KTM when they first came out . I believe excessive horsepower can...
