When Krämer first unveiled its GP2R Proto back in 2018 at the Barber Vintage Festival, the bike was little more than a dressed-up KTM 790 Duke. Stripped of its orange livery and without its factory rider aids, it nevertheless managed to impress Motorcycle.com: “It scrubs speed like nobody’s business, changes direction with ease, and is still plenty quick while still on its side… Opening the gas early and often is mandatory on the GP2, and I was happy to oblige to hear the 790 Twin roar.”
Going on six years later, the marque’s GP2 890 R model makes for quite a different machine. Now based around KTM’s 130hp 890 engine (mostly stock, except for a PASC Slipper Clutch and an adjustable quick-shifter) it comes wrapped in a package of race-ready components. The trellis frame is made from a CrMo steel for increased stiffness, with an adjustable rake that can be tailored to a rider’s desired fit. Instead of storing the gas in the tank, Krämer opted to put the fuel cell in the tail. The XPE plastic subframe holds a little over four gallons.
For its suspension, the GP2 890 R rides on a set of WP Apex Pro 7543 closed-cartridge forks up front and a WP Apex Pro 7746 shock at the rear. Along with adjustable length and preload, you also get some quick-change axles for efficient wheel swaps. Brembo handles the braking fore and aft — through a set of M50 calipers (mated to some 290mm discs) and a P2 caliper paired to a 230mm disc.
Tying everything together is a set of lightweight fiberglass bodywork that comes reinforced with carbon and kevlar. Thanks to the relocation of the tank (a space now occupied by the airbox) and the forged aluminum Dymag wheels, total weight for the bike comes in at just 309lbs. As CycleNews put it, “This is the kind of racer you buy if you’re looking at a long-term project. Not many people have the cash for a GP2, but if you think of this as a turnkey racer you plan on using for the next 10 years in Twins racing classes, like those that compete in AHRMA, it suddenly becomes a viable option.”
This example is VIN: KMC30084513000007. The seller four years ago acquired it from a private party in Colcehster, Vermont.
During his ownership, the seller has covered 2,300 miles. The odometer shows 3,513 miles.
“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 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 moved to an 890RR.
I’ve run this bike at COTA three times and I’m faster on it than my Ducati V4S. With the full Speedbox setup, this GP2 is about as optimized as a single‑R GP2 can get. The lightweight alternator + quick‑turn throttle combo makes it spool instantly, and the Stage 1 cam adds real top‑end power (+7–8 hp).”
Maintenance:
– New clutch pack (by Kramer)
– Valves checked (by Kramer)
– Cam follower replaced (by Kramer)
– Suspension refreshed (front and rear) (by Kramer)
The seller states that there are no known mechanical issues.
Modifications:
“This build uses nearly the entire Speedbox catalog ($9,000 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.
