Kramer Motorcycles has taken on the 890 KTM engine and built an all-round race bike with an extraterrestrial data sheet: the GP2-R. PS was allowed to run in Brno.

The pits roller door is already half open, a narrow panel peeks out shyly in the direction of the pit lane. A few people pass by without taking any notice of her. They have no idea! Although the Kramer Motorcycles GP2-R is still holding, it adapts to its unfortunately still dreary surroundings with a discreet gray paintwork with only a little neon green. Thick fog envelops the Brno Automotodrom and makes us wait. So just take a look first. Every step closer to the GP2-R reveals more of its real potential. We already know the basic concept from the HKR Evo 2-R, a self-made Kramer race bike based on the KTM 690 LC4 engine. Luke “Luki” Wimmer has won two titles in the Supermono European Championship. Mattighofen now has the 890 engine in its range – it goes without saying that Kramer Motorcycles would do something wild with it.

Ergonomics as desired

Strictly speaking, the development of the GP2-R began with the engine of the KTM 790 Duke. Around this engine, the team headed by Markus Kramer designed a completely new motorcycle with a tubular lattice frame plus swing arm and fork bridges. The upgrade to the 890 twin was the logical next step. Like a made-to-measure leather suit, the GP2-R can be adapted to the driver. The offset and steering head angle of the in-house construction are adjustable, as can the strut length and stub position.

Stable lightweight construction

Plus lightweight construction as far as the eye can see. The self-supporting rear also functions as a 16-liter tank and creates space for the airbox and electronics under the GRP tank cover. Otherwise there is nothing to it that is not needed on the track. Everything filigree, but stable: 140 kilos dry. Markus Kramer attaches particular importance to this. Footrests and crash pads are made so massive that slides or trips into the gravel should not cause major damage – we will still test them, more on that later.

Finest hardware

What does not come from Kramer himself is the finest hardware. A Brembo RCS Corsa Corta brake pump presses the pads with Stylema calipers onto slim 290 millimeter discs, the Apex Pro fork and shock absorber come from the upper WP shelf. Of course, there is not an extra gram on the forged wheels, which have long been warmed up by the electric blankets. Finally the fog is clearing.

Puky bike feeling

Mechanic Matthias gives a short introduction to electronics: “Two throttle modes, one aggressive, one tamer, and the button below is for the pit limiter.” The question about traction control is answered with a grin. “We don’t have anything superfluous.” Then he starts the engine and pushes the bike in front of the pits. After works driver Luki has unwound a few laps and given the go, the time has finally come. Sit up, take a short breath and go. In the pit limiter, the GP2-R babbles past the roller doors, demanding attention, that many looks follow it in disbelief.

The first round

Throttle valve on for the first time, into the first few laps. Slowly pre-probing in an inclined position is not possible, the Kramer GP2-R immediately wants a full attack. It follows the pilot’s gaze by itself, draws him to ever tighter lines, begs for more speed from the first second and just doesn’t want a boring warm-up phase. It’s hard to ignore, but at the beginning I urge myself to be reasonable as often as I can. After a few laps no more chance. The more research the gas application, the greater the trust. It is impressive how much traction the Kramer chassis enables in combination with the shock absorber and defines the limit area from the famous highsider curve with controllable slide. 130 PS brutally push the flyweight out of the narrower corners. Yes, a 1000 has more power – but it can only play that out from the middle of most of the straights. The GP2-R may lose a little in terms of lap time, but it is ahead in terms of pure experience. Also because you let the gas stand when the superbikes have long since dropped anchor. The 140-kilo rocket can be compressed hard. To call your braking system snappy would be as understated as a MotoGP bike is “powerful” to call. The stoppers have literally easy play with the bike, put the GP2 jerk on the front wheel. craziness!

Readjust once, please

Only one thing I don’t like yet. When decelerating to the apex of the curve, the bike braces itself harder and harder against turning in as the speed increases, then falls inward when the brake is released. Given the otherwise dominant Puky bike feeling, this is probably a setup issue. On his return Luki is already sitting thoughtfully in the box. When asked about the problem, he says: “I’m already thinking how we can get rid of that.” After a brief consultation with Matthias, adjustments are made, the preload and damping of the fork and shock absorber slightly changed. With success, the feeling on the second run fits better, but the GP2-R does not want to be precisely positioned on the brakes. The reason: The long and hard braking maneuvers in Brno require stronger springs than the built-in springs at the front so that the fork does not dip into the corner at the entrance to the bend. As Tobi later confirmed in the editorial office, this problem did not arise during the test in Anneau du Rhin. The setup was right on the comparatively small course. Attitude is rewarded For the hobby racer, the fact that the GP2-R properly educates its driver is much more interesting than the details of the set-up. It rewards clean style with traction and stability – and vice versa. Briefly not pushing the upper body far enough forward in an inclined position means, for example, restlessness and loss of grip on the front wheel. The bike speaks to you like an instructor, forcing you to pay attention to posture if you want to be fast. However, the slightly modified 890 does not overwhelm you during this training, but provides controllable power at all times.

Rennsemmel in the gravel

Anyone who still has doubts about the performance of the GP2-R will be cured by Luki. Incredibly oblique (see picture above left) and he quickly circles the course with her. In the final endurance race, which we drive in a duo, he is now even in the lead against the 1000-strong competition and hands over to me in third place. Now is the time. I can’t defend my position for long, instead I find out that there are braking points that are too late for the GP2-R. As the fuel level in the rear drops, the center of gravity moves noticeably forward and the tendency to stoppage increases. A little too brash because the brakes are too late, and the stern climbs steeply towards the sky. Release the brake, land again – the bike stabilizes immediately, but the gravel is close. Fortunately, the GP2-R and I had already reduced a lot of speed – two strokes of the handlebar in slow motion, then a gentle serve. Except for minimal scratches, nothing happened. Pick up, carry on – that’s the way it should be!

Conclusion

The Kramer Motorcycles GP2-R also delivers what its data sheet promises. The extremely low weight translates one-to-one into top handling. For really fast laps, the setup has to be right. The bike educates the rider in many ways. Good setup work is rewarded with neutrality, a clean posture with stability. Constantly dealing with your own style and coordination become a duty, and the training effect is immense. A lightning-fast burner comes from Kramer Motorcycles and maybe also from KTM.
