Just like the 2010 BMW R1200GS series, the 2010 BMW R1200RT features BMW’s new 1,170cc flat-boxer motor with a DOHC head arrangement. This also means that the RT will make more power across the power band, with peak power making 5hp 3lb•ft more over last year’s model. Unlike the GS though, the RT comes along with more than just a new motor. More on that with 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.
