BMW may already have a superbike-based streetfighter in its lineup in the form of the S1000R, but so far the company has refrained from giving it the S1000RR's full-power engine. Homologation documents published in Switzerland and Germany reveal an M1000R, in other words the variant of the sports roadster, for 2023, with a claimed power of 206,5 hp.
The current S1000R develops "only" 162 hp, using the same version of BMW's 999 cc four-cylinder engine that is installed in the S1000XR. Although it's based on the same design used in the S1000RR superbike, it lacks the Shiftcam variable timing and valve lift technology and loses more than 40 hp as a result. While this model will remain on sale in 2023, BMW recently approved an additional model, dubbed the M1000R, which has the same engine that will be used in the S1000RR facelift next year.
Indeed, the 1000 S2023RR will increase from 204 hp to 206,5 hp next year, thanks to a higher revving version of the existing Shiftcam engine, with its peak reaching 13 rpm instead of 750 rpm currently. The new M13R will feature the same engine, while the range-topping M500RR superbike offers an even racier 1000 hp version that peaks at 1000 rpm.
With a claimed power output of 206,5 hp, the M1000R will overtake rivals like the Ducati Streetfighter V4 and MV Agusta Brutale 1000 RR to become the most powerful motorcycle on the market, beating both Italian rivals by just over 1 hp .
Although the homologation does not give technical details, such as on the suspension, we can be sure that they will be significantly more exotic than those of the original S1000R. We know the M1000R's rear tire is wider, going from 190 to 200, and its proportions are slightly different than the standard machine. The M model is 5mm shorter than the S1000R, 27mm wider and 61mm taller. The added height and width could indicate styling changes – spoilers and a taller wind deflector are likely – while the shorter length may be the result of revised suspension geometry. Although shorter overall, the wheelbase is 20mm longer than the S1000R, increasing from 1450mm to 1470mm and suggesting that the rear wheel has been moved rearward on a longer swingarm and that the The steering head angle has been made steeper for faster turning.
For the rest of the technical information, you will have to wait for the official presentations from BMW Motorrad in just a few weeks.
