Performance question: Low rider
HD's website doesn't give horsepower ratings of their bikes. Just torque @ rpms. The Low Rider give torque @ 3500: 102. Roughly 68 horsepower.
The bike weighs around 660 pounds in stock configuration.
What are the performance mods to increase horsepower, easiest to the hardest?
What mods to put out in the neighborhood of 100 hp?

Headwork, cams, more compression, good slip on mufflers, & a tuner will get you there.

if you are looking for a 9 sec 1/4 mile bike, this is not your machine, however if you want a really fun bike to ride that has decent performance stock, it is a good choice, and can improve performance with a few simple mod's.

Easiest and cheapest solution is to buy a Yamaha R1M; if horsepower is your only goal go all the way and save yourself a buttload of cash in the process...
Edit: If horsepower was my goal, I know what I'd have. HD, horsepower... yea right...

Never "strain" to get your knee down. What that rider is doing isn't necessary. Looks silly too. When in a lean, let the asphalt come up to meet your knee. Never "reach out" with your knee to touchdown.
Good riders can corner quickly, without putting their knee down.
Now, as far as the "horsepower wars," Harley doesn't publish HP #'s because their engines only rev to 5500rpm. (Give or take.) Everyone else is at least double that.
The number's they generate are not impressive compared their competition. So, they publish torque figures instead. Big HP #'s are created by strong torque spread over a large RPM band. Harley's have a short RPM band, by design.
Harley's with their "primary" case being outside the transmission, then directing torque back into the trans case, is very inefficient. This is the reason the Sportster outperforms the "big twin." cc for cc.
