2005 BMW R 1200ST and R 1200RT

If this new RT had been available last August, I honestly believe it would have spanked the competition in our 2004 Sport Touring Comparo, since it addresses our two biggest complaints (lack of power, and harsh brake linking) with the old R 1150 RT. If the R 1200 RT's boxer twin could sing a beautiful Italian baritone, it might even knock Aprilia and Ducati completely out of the sport touring business! It's that good. Then again, this sort of excellence is expected in the $17K+ price range, and it's nice to finally see BMW deliver.

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.

The new ST's suspension is a little on the soft side, but still offers good control, as long as the rider is smooth.

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.

Though it's unlikely to win prettiest bike at the ball honors, we think the ST looks best in the Dark Graphite / Piedmont Red combo.

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.
