    Hello all, Whenever I ride it seems as though I get a fair amount of road grime and dust on my rims more so on the rear rim than the front of course. How do you guys clean your rims from this road grime?

    Front Tire Valve Core Came Loose

    Context: I have 2017 KTM RC 390 with Dunlop Q3+ and Puig metal valve stems (https://www.revzilla.com/motorcycle/puig-90-degree-valve-stems).

    The Definitive ABS Removal Thread

    I’ve searched extensively on this forum, the duke 390 forum, and the internet at large, but still have some questions. There is surprising little in the way of real information, other than complaints about how difficult it is to access and remove the unit itself. Please don’t hijack this...

    Front Brake Rotor and Caliper Upgrades

    I am upgrading master cylinder, brake lines, and brake pads. I was wondering if aftermarket front brake rotor, e.g., Galfer rotor, would further improve braking performance over 320mm stock rotor. I am using the bike only for the track and the stock front brake really sucks. Are there any...

    Engaging front ABS on track

    I engaged front ABS quite a few times on track after straights; I didn't even realized that I am braking hard and it didn't felt that I am braking hard, but the ABS still engaged. Is the ABS on 2017 RC 390 conservative, so it turns on before the wheel locks up? I am removing ABS, so I wanted to...

    Front Brake Lever touching throttle at trackway

    I am using my 2017 RC 390 for track. As the track day goes by, my front brake lever becomes spongy and the lever touches the throttle. I changed brake fluid to Motul 660 this morning in the hope that brake lever feel would get better. The feel is better, but if I put enough pressure I can get...

    Is it at all possible to remove the headlight cluster?

    I was wondering if it was at all possible to change the front of the RC to more of a street fighter type setup up front with a big round headlight, and maybe change the tach and speedo to smaller streamlined units, is that possible at all with the RC's front cluster setup?

    2017+ EBC HH Front Pads

    Can anyone confirm if EBC makes their sintered HH front pads for the 2017+ RC390n and if so, what is the part number? I've seen the ones for the 2015-2016 with part# FA606HH but don't see ones for the 2017+ year model. I've used those pads on all my track bikes and have been really happy with...

    RC390 Front Disc possibilities

    Hi guys, I am planning on upgrading the braking power on my 15' RC390 for the front. I saw that the most common modification is to buy the Powerparts (Galfer) 320mm disc but I was wondering if others 320mm disc from other bikes would fit? Thanks.

    520 16T Fronts

    To add to the mix, I'm now also producing a Chromoly 4140 Hardened Rockwell 36C front sprocket for the stock 520 chain. These sprockets are hard clear through, not case hardened as most front sprockets are. This means it'll last a LOT longer. Going up to a 16T front is basically about the same...

    272.7 lbs with 2/3 of a tank of gas

    272.7 lbs with 2/3 of a tank of gas -at least that is what the math said after I subtracted the weight of the board the bike was sitting on. I’m not bragging and my goal was not go to great lengths to try to lighten the bike. This was merely a labor of love of tinkering and aesthetics. This is...
