If you’re looking for a GP2 that’s already been taken to the absolute limit of what a single‑R chassis can deliver, this is it. I’ve owned this 2020 GP2 (Chassis # 007) since 2022, and the majority of the upgrades and maintenance were completed over the last two track seasons. Bike is in excellent condition and needs nothing. Only selling because I purchased an 890RR.
This build uses nearly the entire Speedbox catalog ($9000 in speedbox parts alone, labor not included), and the difference is night‑and‑day—faster spool, sharper response, stronger top‑end, and dramatically improved cooling efficiency. It’s the most dialed‑in GP2 you’ll find without stepping into RR territory.

Track Performance
I’ve run this bike at COTA three times and I’m faster on it than my Ducati V4S. The lightweight alternator + quick‑turn throttle combo makes it spool instantly, and the Stage 1 cam adds real top‑end power (+7–8 hp).
No additional spares included beyond what’s listed.
Pickup in DFW area, 76092. I can assist with delivery within a 200 mile radius of 76092 if paid in full ahead of time.
If you want a GP2 that’s already built right, already sorted, and already proven on track, this is the one.
ASKING $21,500.
