Sweet bike man 😎
Thank you!
Looks real good. Hope it rides as you want it too. I’m just embarking on my RC build now. Enjoy.
It’s one of the best small cc bikes you can get
nice bike..rc390 racebike user here in the 🇵🇭
💩
Love it! We did a lot exactly the same. Great minds think alike!
Yeah man! Would have been nice you lived near to compare them on track. Where are you from? Awesome build by the way, I watched the whole series
nice!!
I would love to put a KTM 300 2-stroke dirt bike motor in it or the 550 they did years go to stroke implant
Crazy!!! 🤩🥳🤯
That's what I need man. Sweet Bike
After owning many bikes, this is the best Track Bike I’ve ever ever had
@@4strokehearts I have ridden a non prepped one and that chassis is just so sharp I loved it. Just can't imagine how it handles now with so much weight loss 🥵
nice
Any chance you could share details on how that koso gauge was installed. I have the same gauge but was told that this bike does not operate without the OEM installed. Thanks
Here is the link to it kosonorthamerica.com/product/rx-2nr-gp-style-tachometer-16-000-rpm/
When you see the site you will see several sensor connectors, (temp / rev / speed) you want to splice these wires from each sensor in the engine side and connect each one.

this should help
Nice bike sir👍 I'm 6ft 200lb what do you think about a bigger guy riding one of these? I just want to do track days maybe a few races
Hi Richard! Although this bike may seem smaller compared to the R3, or the Kawasaki 400, the ergonomics are very similar. You will fit just fine. I prefer this over their competitors because the frame is made for racing first and Street second they are three or the Kawasaki need a bunch of mods to turn them into track. Yeah. If you can get a hold of a cop bike, it’s plug and play.

This the real race bike.. not the new design 🤣
This is a full race build from a 390Cup yup!
whats the kerb weight after modified?
Just over 280

Standalone ECU, piggyback unit or remapped OEM ECU?
Power commander 5, piggyback is ok but for a little bit of more money you have the power commander option. I have mapped it to the current airbox and exhaust for a mix of 110 + 91 50:50 it’s the best way to keep the bike healthy on the inside
@@4strokehearts ahh right, I missed you mentioning the pcV. Thanks.
@@MHeXtreme442 ✌🏽
what size tires and what air pressure for track???
120/17 and 140/17 I run Dunlop so 26 cold and 28 hot rear and 28 cold 30 hot front
Would you recommend the wheels? Can you compare?
Since overall I lost about 80 lbs from the original cup setup, I notice it due to the amount of things collectively done. But what I noticed the most is the braking, the centrifugal force is the biggest difference. My wife has a standard cup and when I ride them back to back, it’s a massive difference. Specially in hard braking whilst tipping in and doing switches left to right and right to left fast. Honestly? If you want to dump 2-3 grand on wheels I would suggest you spend that in other things, like fairings, exhaust, stays, clipons, ECU, etc… if you have done all that already and wanna push further then yes, I’d highly recommend.
Bummer it’s not the ‘22!
Something better ;)

Bro what's the top speed...
It all depends on the gearing. When I use 15/44 it can do 108 MPH
Where can i get the rpm meter

Tanks bud ❤
Wouldn't it been easier to start with chassis, and build up from there verse stripping everything off of the bike??? Just seems like you got rid of everything factory to begin with.
Oh no, everything important stayed
How much were the wheels ?
3k
@@4strokehearts almost the price of the bike lmao
