2005 R 1200 ST

The new R 1200 ST replaces BMW's R 1150 RS model and is aimed squarely at Honda's Interceptor (VFR), with additional targets being the Ducati ST-4S, Triumph Sprint ST and even Kawasaki's ZZR-1200, according to their chief designer.

As you probably know, those are some lofty targets. To facilitate this newfound ambition, BMW has redesigned the old R 1150 RS so extensively that they claim it is "100% New".

For contrast, BMW says the new R 1200 ST is 12% lighter, has 14% more horsepower and 17% more torque than the R 1150 RS.

This works out to a *claimed* 110Hp & 85LbFt at the crank, coupled with a dry weight of 452Lbs. I may have been a bit skeptical during the presentation, but I was positively astounded to find that it actually felt more like a 50% power and weight improvement once I was on the road. Bravo!

We just received an R 1200RT for further testing, and the first thing we did was strap it to our Dynojet.

It appears that BMW was spot-on in their estimates; our new R 1200 RT just cranked out an honest 102.95Hp @ 7,300rpm and 80.95LbFt @ 6,250rpm at the tire.

These are some mighty impressive numbers for an air/oil cooled boxer-twin, and since the ST shares the same motor tuning with the RT, these numbers should apply to both models.

That new found power is generated by an 1,170cc air/oil cooled boxer-twin similar to the unit in the new R 1200 GS, but tuned for more high-rpm power and equipped with a second oxygen sensor to provide better fuel mapping. Not surprisingly, the result is quite similar to the GS' motor, but with a bit more willingness to rev and a power delivery optimized for effective thrust in medium to high speed corners.
