stock

So as many have undoubtedly noticed, over the last month or so, Tyga and Formula390 have been in negotiations for a US distribution agreement. Well, a deal was struck, a massive initial inventory stock of parts was ordered, banks wrangled, and I can now FINALLY announce that Tyga USA is a done...

Bike was having issues cutting out at 6500 rpm during my race Sunday. Would happen at 6500 but not every lap. Bike was also not idling worth a shit, while idling at ~1800 every other second it would have a hesitation and drop to ~1200 once the bike was warm it wouldn't stay running at normal...

sold it all

Coming soon. RC390 top triple clamp and handle bars. All specifically designed for the RC390. The whole assembly is lighter than the standard setup, and with the bars being seperate from the top clamp, there's no worry about breaking the top clamp during a crash, which is going to happen on the...

I did a little write up of Master Cylinders for the Aprilia Forum. Since the front brakes on these bikes are very similar this information could be useful for some folks over here too. If you feel compelled to tell me that your stock brakes are just fine please refrain. I don't need to hear how...

What's the stock chain / sprocket size? 520?

Crashed and broke my rear brake lever. Does anyone have a stock one? If you want to keep the rearsets all as a set I can purchase those as well.

Can someone please help me? For the life of me I can't figure out how the left fairing stay attaches. I have stock rearsets. Pictures would be nice for all the connections. Also tyga I'm a little disappointed it doesn't come with instructions.

Forum member Fasteddy has been on us for a while to put these out, and we've finally finished them up... These 6061 hard anodized billet spacers install cleanly under the stock mirror, putting them in a position for a much cleaner viewing angle (lower and wider) on the sight challenged RC...

Anybody get more than 5k on the stock tires? My rear tire is showing cords after a little more than 5k and needs to be changed. Kept 'em @ 29psi the whole time. Manual says Metzler Sportec M5 (which most places are out of stock) but mine came with Pirelli Diablo Rosso II so that's what...

Had 5 in stock...Motorsports Nation Plainfield, CT

Hey guys. My 1000km service is nearly due, and from what I've read about the akra map, I reckon I'll get it uploaded to my street stock RC. But I have a few queries, does it run better? Or to lean without the Akra pipe?

Placed an order on these and only took 2-days Fed-Ex from Germany. These are the European spec turn-signals.The fronts come as just the L.E.D. bulb part that bolts-into your stock U.S. spec rear-view mirrors. The smaller rear L.E.D.'s replace the larger, O.E.M. incandescent bulb ones out back.

Anyone need a stock rear shock for experimenting on, or anything like that? I'd love to get it outta the garage. I have no idea what the thing is worth...100 bucks plus shipping? It had about 300 miles on it before I replaced it with the Penske unit. Let me know if you're interested. Eric

I'm excited to announce Formula390 has signed a dealer agreement with JRi for the RC390, and as part of that have also arranged with them to be able to do an offering to the forum members a group buy for the Double Adjustable w/Remote shock. The normal price for the JRi Double Adjuster is $899...

MNNTHBX - Enter We have the country's first inventory of Bazzaz ZFis. We can carry the others, but we've always been huge fans of their product and support, easy install, and ultimately, the performance. Full disclaimer... We wanted to test a package we felt would provide the most bang for...

I wasnt sure exactly where to post this, but I bought a 43T rear sprocket to put on the bike and kinda like the stock rear sprocket color. My new one is natural aluminum and wondered if anyone knew if the stock one was powder coated or painted or what? Just wondering, I might make the new one...

Took my KTM to the track on the weekend and it handled great. Can't say enough good things about how well the stock suspension (forks/shock) worked with the Pierelli Super Corsas. However, the power was just not there. The bike had no power and farted/backfired when rev'd hard. I only saw 89 KPH...
