I love my little CBR. It's fun, slick looking, and very economical. The only thing that I really wish, is that I wasn't at around 7,400 ft. Being at this altitude means that I only have a theoretical 18.44 HP. Sad day. I'm stoked for when I move back east in a few years to see how the altitude changes the performance... that or I'll just have to take a road trip to the west coast.

To figure out your HP at altitude, you can use this calculator or use the formula itself:

(((HP x Altitude) / 1000) x .03) - HP

I'm showing about a 22% loss in HP where I am, how about you guys?

Shhhh! Don't break the illusion that we each get the official hp rating. I'm at 1800ft and I get 23.7hp.

With a few neat stickers and a tinted windscreen, it should put you back to stock HP.

I hear that if I had purchased the Red model, I would have gained 2x the HP.

Sorry to brag, but sea level baby! Also after market exhausts add like 20 HP

EYVoom, how is the condition of the road from Minturn to Leadville? I haven't been up there in years, but as I recall there are some pretty nice turns on it. Last time I rode it, I did a big loop, from Avon to Leadville, over to Independence Pass, down into Aspen, then on to Glenwood Springs and back to Avon. A long, but fun ride.

I just got back from my regular sunday ride up and down the ski basin road. Three round trips today. Just over 10,000 feet at the top, and 7500 at the bottom. Needless to say the downhill run is a blast. Although there are lots of great roads all over the U.S., and many of them down near sea level, not everyone is lucky enough to live close to where the premium roads are. I wouldn't trade these mountain roads that are literally in my backyard, for straight and boring flatland roads near sea level. Just one of a few of the reasons I moved from the midwest a long time ago. Nearly every place you go in the Rocky Mountain west looks like a picture postcard. I really like that.

23.6 HP , average elevation here is around 150ft , I'll have actual dyno numbers soon though.

Gravity, in the form of 6 to 8 percent grades, more than makes up for the slight decrease in horsepower out here in the Rockies.

I live between the the Selkirk and Purcell ranges. Although the peaks can be in the 10,000' range, the roads rarely get above 5500'. Still, it is hard to maintain a good speed on long uphills into a headwind. You may want to try a 2 tooth larger sprocket on the rear....and stick with 85 octane fuel.

I feel ya, I never go past NewCombs (4,000ft) on ACH. After that you ascend to 8,000ft and this bike can NOT handle it gracefully. On the first half of the mountain though, its awesome.
