Four years ago the BMW S1000RR took motorcycling's super-sports class by storm thanks to its unrivalled combination of power, handling ability, sophistication and competitive price.
We've waited longer than expected for a naked follow-up based on the 999cc, four-cylinder engine and lightweight chassis.
This combines with the bike's light weight (at 207kg with fuel it matches the S1000RR) and efficient, quick shifter-enhanced gearbox to provide fierce acceleration.
Yet the Sport is also very controllable, backed up by the efficient yet unobtrusive traction control system.
It lacks the RR's manic top-end charge but, for roadgoing use, more than makes up for that with its additional pulling power.
Throttle response is excellent, making smooth, strong torque available everywhere from below 5,000rpm to the redline.
Price is where the BMW lands a final blow to an already bruised opposition.
At £9,990 the basic S1000R is competitive with bikes of more modest abilities.
THE FACTS BMW S1000R Sport ENGINE/TRANSMISSION 999cc four-cylinder four-stroke, six-speed transmission PRICE/ON SALE £11,390 (standard S1000R £9,990)/March POWER/TORQUE 160bhp @ 11,000rpm/84lb ft @ 9,250rpm TOP SPEED 160mph (estimated) RANGE 140 miles @ 40mpg (estimated) VERDICT Thrilling high-barred sports bike with scorching performance, agile handling, sophisticated electronics, reasonable practicality and very competitive price TELEGRAPH RATING Five out of five stars THE RIVALS Aprilia Tuono V4R ABS, £12,432 The S1000R's closest rival in terms of performance, features and price, Aprilia's refined, 170bhp V4 is more expensive but still worthy of serious consideration.
BMW K1300R, £12,125 BMW's own super-naked opponent makes 173bhp and is very fast, but it's bigger, 36kg heavier, more expensive and lacks its newer sibling's agility and refinement.
The Sport costs £11,390, giving it a distinct advantage over the best of its super-naked rivals.
That price looks like a bargain for one of the fastest, most refined and above all most exciting bikes on the road.
Pressing the handlebar button to select Dynamic or Dynamic Pro mode firms the suspension, recalibrates the ABS and turns the BMW into a superbly agile, firm and responsive sportster.
