BMW G310 R revealed
Production version of BMWs 313cc singlecylinder concept finally debuts
HERE’S BMW’s G310 R, the production version of the single-cylinder roadster we’ve seen in spy shots and as a concept.
The product of a partnership with Indian manufacturer TVS, it's got a 313cc engine with a back-to-front cylinder, the exhaust exiting from the rear, and making a claimed 34hp and 20.6lbft.
That's up on some of the similarly-sized single-cylinder competition, like Honda's CBR300R, at 30hp. But it's about 10hp down on KTM's RC and Duke 390 and Yamaha's parallel-twin YZF-R3, probably the most exciting current offerings in the sub-500cc market.
Honda has also revealed a new twin-cylinder CBR250RR concept, so the question for BMW's long-awaited first assault on the sub-500cc sector could be: is it enough already?
The claimed top speed is 90mph and fuel economy 84.8mpg.
It's got a tubular steel frame, upside-down fork and aluminium swing-arm. It comes with ABS as standard, delivered through a radial-mounted four-piston caliper biting a single front disc.
The seat height is 785mm and BMW says the styling echoes the S1000R. See a full gallery of pictures below.
Price is to be confirmed.
