Horsepower Lab

Whether you want a touch more power to pass that semi on the way to Laconia without downshifting, or need enough torque to slow the rotation of the planet* so you are not late for that date we can make it happen.

From simply fine tuning your ride to get better fuel economy, adding pipes and an aircleaner to get a touch more power and sound to a complete power build Chicago Harley-Davidson is the only place to consider for your performance upgrades. With our in-house machine shop, years of experience and unmatched dyno-tuning abilities there really is no other logical choice.

Unlike other dealers we won't put a bike on our site unless we did the work on it. We're not into bragging about mediocre performance and low numbers of bikes making real power either. We're into making bikes perform. We have more customers in more states (and countries) making more power per cubic inch on pump gas than every single bike on other local dealers sites.

Street reliable 100whp 88" bike? Done.
Daily ridden 120whp 103" bike? All day long.
140lb-ft of torque from a 113"? That was us.
1.6whp per cubic inch naturally aspirated? We've done that already too.
Tune a bike to break a Bonneville land speed record? Check and Check
Tune a 161mph Softail? That's so last year.

We offer ready to go parts and tune packages if you have a new bike with nothing done as well as custom build consultation to get you the power you want where and when you want it.

*rotational slowing may not be noticeable and depends on travel direction.
