BMW Motorrad is reporting that worldwide motorcycle sales were up 21% for the first five months of 2010, compared to 2009’s numbers. Sales were up 19.3% for the month of May alone, with 12,139 units sold, making for 45,431 units sold thus far in 2010. The newly revised BMW R1200GS/Adventure models account for 3,705 of the motorcycles sold in May, which is up almost 34% from last year.
While the GS comprises almost a third of BMW’s total sales in May, BMW reported that the F and K series motorcycles also showed strong demand in the month as well. Also making a strong showing is the all new S1000RR superbike, which sold 1,345 units in last month for a total of 5,236 units sold this year so far.
BMW released this week its next evolution of the R1200GS & R1200GS Adventure motorcycles. Both bikes, along with the entire R-Series range, will feature BMW’s revised 1,170cc flat-boxer motor, which has increased horsepower and torque and a DOHC head design. Beyond this the bike is pretty much unchanged, sans some other minor updates. Details and photos after the jump.
The rumors appear to be true, and the BMW R series is getting an update to its motor for 2010. Maintaining its existing 1,170cc displacement, the most notable change to BMW’s flat boxer motor is a dual-overhead camshaft (DOHC) cylinder head setup, which was previously only seen on the HP2 Sport.
With the bore and stroke staying the same for 2010, the R lineup will continue to use the same 101 x 73mm cylinders, making a total of 1,170cc’s. The real changes and improvements come from the new cylinder head design. The DOHC design features two chain-driven camshafts, with each camshaft controlling both an intake and exhaust valve in the radial four-valve head.
