Well I rode my BMW K1100LT 200 miles to my parents place yesterday (I'm typing this on my Mom's Mac) and was thinking of stuff like this. Now at 120 KPH (about 75 Mph, I'm guessing) my engine is doing 4500 RPM in 5th gear. Redline starts around 9000 RPM, so in theory, my bike will do about 150 Mph by the time I get to redline on the tach.
I've no idea what kinda BHP it's producing, but I'm guessing it's around 100, which is not all that much for an engine of this capacity, but for a naturally aspirated 550, I'd say it's damn near impossible, when Mike Rieck's "Million Dollar CB750" with just about every performance accessory money can buy (not to mention hundreds of hours of his own talented performance mods) is "only" producing 98? (which is pretty bloody amazing since thats more than TWICE the RW BHP of a stock CB750)
Having said that, I think some folks here have been doing a shade more than just some "Good natured ribbing", and should take a step back. I'd like to think that we're all friends here, but some of the posts have been less than friendly, and not in the spirit of fellow motorcyclists enjoying each others company. If you don't agree with someone here, say so and move on, there's lots more to see here folks, so don't dwell on the negatives. Cheers, Terry.
