If the R1200R horsepower hits 109 that'll be pretty impressive. Especially for an air-cooled engine. ****, Harley's air-cooled twins make a little more than half of that. Says a lot about both companies, doesn't it?
H-D's massive sales numbers also say a lot about what people desire - and hp is not always a main issue..............
A Sportster 1200 will show about 64 ponies on a dyno. The R1200R will probably show 92 or so when reports start coming in. The Sportster engine has pretty impressive pull from 2,000 - 3,500 rpm and redlines at a low 6,000 rpm, well suited to a leisurely pace, vs. a sporting pace. Two different animals for two different riding styles.
My Buell XB12Ss weighs about 470 lbs. with fuel, redlines at 7,100 rpm and made 88 hp on the dyno, probably fairly close to R1200R performance overall - all based on a slightly warmed over Sportster engine with 10-1 compression.
It's hard to beat the R1200R styling and the 6-speed - it's just an incredibly nice machine from front to rear. The single flaw it has is the farty exhaust, everything else is perfect in my book.
