Nonetheless, when allowed to roam free and uncorked, BMW says the new S-thou has met the 1-second-faster goal around all the tracks it has tested at. An impressive feat, for sure, but maybe more impressive is the weight loss plan the new bike was put on. From the outset, sportbikes are designed to be as light as possible, so to shed 25 pounds is incredible.
To do this, the new S1000RR had to start with a clean slate design; nothing is shared between old and new models. The aluminum frame, dubbed the “BMW Motorrad Flexframe”, is all new with tuned flex characteristics for better handling. In the process of tuning this flex, wall thickness was taken into consideration, with the final frame weighing 3 lbs less than its predecessor.
A new trellis-type subframe is used, and weight was taken off as many places as possible – including the wheels, suspension, even the fairing thickness – to achieve the 25-pound total weight loss goal. The chassis and suspension changes alone account for 11 lbs of that diet. Opt for the M performance package and you’ll see a further 7 lbs chopped off, thanks to carbon fiber wheels and a lithium-ion battery. The M package also gets you an adjustable swingarm pivot.
