Who can recomend a nice short throttle for The Rc390 Just dont want no throttle stricking issues Stock throttle is just way to long

Stock gearing should defenitely be 44t or 43t 45t is just to short for Any kind of street riding Highly recomend changing to 44 or 43 so your engine is not so overreved all The time

Let me know if anyone is interested in getting rid of their nearly new stock tires for cheap. Thanks

Quiet a few new items just hit www.mnnthbx.com with competitive pricing, and always in stock.

For those racing with these tires please states tire compound, climate type and tire life. I'm doing first trackday on RC in couple weeks with stock tires and I expect that they wont be suitable. I'm curious how guys here on running on the supercorsas. Thanks in advance

Want to resprung and re-valve the stock (non cup) front fork. Anyone who 've done the upgrade can tell me whether it is cartridge or damping rod?

We have thin gaskets and timing chain tensioners in stock and active for sale on the site now. If you plan to purchase my engine kit piston/cams/etc these items are included, meaning don't purchase separately now. These items are for club racing rules(retaining stock piston/cams), track days...

So I have used these on ALL of my bikes and never had any issues. Figured I would give them a shot on the RC. Ordered from ebay and expected shipping was over a month from china... pleasantly surprised to get them in the mail only 9 days after ordering! cnc'ed anodized adjustable shorty levers...

So whats the verdict here? I have read the bike does and doesnt need to be remapped when you install an aftermarket exhaust. I know the Akro exhaust has a remap... but I am not looking to spend that much, plus that can is HUGE. Not a fan. I am interested in the AHM ZR1 exhaust, or even the GPR...

I bought a set of the rear-sets KTM offers for my (street version) RC390 from the catalogue, it's the same that comes on the cup-bike stock. Beware, the directions ask you to remove the threaded collar from the stock piece and put it in the new part, problem is, it is the wrong thread...

Just as an FYI for the group... I've been working on developing a new exhaust which will ditch that huge stock 5.2kg boat anchor of a muffler and replace it with a new muffler which will still fit into the stock location. This primarily means no huge can hanging off to the side of the bike to...

I'd love to get rid of the stock tires, the Pirelli Diablo Rosso 2's, if anyone wants them. If you pay for shipping and whatever it costs me to package them up, they're yours. They have 120 miles on them. Send me a PM if you're interested. I can send you photos, get a shipping and packing...

If anybody wants to get rid of their stock windscreen I'll buy it. Also... is there a classified section on this site? If there is, I can't find it.

Long awaited on both ends. I installed the pcv on a cup bike here. The throttle stop has been removed. Couple pieces of data, initial data is bone stock out of crate(stop removed), stock air filter and lid, dB killer installed, with Akra map. Graph shows "stock" this bike vs fully tuned (with...

First, I do not work for Commonwealth Motorcycles. I'm an independent road racer and M/C endurance team owner. This is a first update to the install I did yesterday on our RC390. Got this kit due to vague up shifting we experienced at race pace. Sometimes the shift would fall back without...

Finally found some time and got the front forks completely disassembled. I now have a front spring swap for the stock forks.

We were at Willow Springs 4-24,24,26 AHRMA rounds. Stock gearing left Nicole hanging out at 500 under the limiter from T7-T9. 4-20 to 5-1 we ran at AHRMA Sears Point (Sonoma) and the stock gearing was pretty much there. The AHRMA SOS2 450 single motors were no match, but our handling was...
