RIDE REVIEW I 2024 KRÄMER GP2 890 RR P 7 6 290mm discs and Brembo RCS 19 span- and ratio-adjustable master cylinder. "We are look- ing at an optional brake kit for 300mm discs if a rider is at a track that's hard on braking or for someone who wants more braking capacity," Karvonen says. "The focus on staying with 290mm discs is mainly to keep the weight down because the bike is lightweight. The rotation - al mass is so huge on the front end, and it's very noticeable going from a 290 to a 300mm disc." The rear brake remains un - changed with a single 230mm full-floating disc with a Brembo P2 caliper. B O D Y W O R K + The top fairing on the 890 RR is significantly wider than the 890 R's. Beautifully devoid of the dreaded winglet craze sweeping the world from MotoGP down, the RR's wider top fairing adds a claimed nine percent more aerodynamic efficiency and a nine mph higher top speed. The fairing also puts added oomph into the RR's ram-air effect. "The airbox itself with the new bodywork is completely different," Karvonen says. "Not just the exterior, but the way the base of the airbox mounts and where the air filter fits to the throttle body is different. We've integrated the ram-air ducts more directly. It's not a pressur - ized airbox, but it's more of a force-fed airbox now. We tested it, but we didn't find a lot of advan- tages to the pressurized airbox in this drive train. So, we've stuck with a fairly simple cold air feed." F U E L TA N K + One of the design trademarks of a Krämer is the subframe and seat unit doubling as the fuel tank module. At 4.2 gallons, its capacity to the 890 R remains unchanged, but larger 48mm throttle bodies meant a more powerful fuel pump was re- quired, up from 3.5 to five bar. "It's quite a bit higher pres- sure than the previous fuel pump, and it also is larger," Kar- vonen says. "The way it mounts You can see how much room there is to move on the Kramer chassis here.
