I just picked up a second RC390 for a few aftermarket goodies that my current race bike is missing. The new bike will be getting a freshen up before it gets resold. The fairings have already been painted a flat black but in the process of choosing a color for the frame and wheels and looking for...

Larger front sprocket or smaller rear sprocket. Depends how much extra speed you want. It will negatively affect your acceleration though

The engine cases are for a ‘17+ RC 390 & 13+ Duke 390, perhaps they changed the engine cases when they added the slipper clutch (which the duke 390 was already using).

Hi, I’ve bought an RC390 to turn in to a race bike. It’s vin plate says it’s a late 2016 model. I recently purchased GB case covers to put on (I ordered a set supposedly for 2014-2016 models), the right side looks like it lines up perfectly but the left side does not. This lead to my question...

Maybe just go a smaller rear sprocket? Vortex rear sprockets on eBay from 38T upwards Edit: driven have 16T front sprockets

Don’t you need engine covers with your race org? And did you experience any clearance or positioning issues with the stock rearsets? Looks great [emoji106] any pictures with the belly pan on?

You won’t have any power gains without a tune, it would be a waste of money buying a filter and not getting a pcv + tune. Advise I received from a fellow forum member @=Maz= + racer was “do not ride the bike until it has a pcv + dynotune”. Whilst street riding won’t put the same stress on the...

Fantastic video [emoji106] I tend to be a lot more focused after a crash and will generally set faster lap times on the very next lap. 90% of my crashes I’ve walked away with minimal or no pain so they don’t really shake me up and it’s just a matter of fixing the bike (usually with tape & cable...
