and 108 lb-ft of torque with the stock cylinder heads.

Hope this helps

 

I'll agree that this kit makes good numbers but to be honest it's mostly coming from the 11.25 compression. If you would have used a aftermarket cam and a bigger 58 mm throttle body with that much comp. number would be 120hp and higher on tq.
Again great numbers just hadn't seen a stage III kit like that with the comp. offered from HD. The water cooled heads will offer up a lot more options as far as build goes by being able to run more squeeze due to cooler heads.

 

Picked my bike up after 6 months in hibernation. Couldn't wait to see what it could do with the 110 horses. All I can say is "WOW!".


Runs great and tries to jump out of it's skin when punched at 3,000 RPM's. Couldn't be happier with the performance!

 

It's not street legal. That is what the crossed flags symbol next to the item in the catalog denotes. Not that, that would stop me from riding it on the street anyway.
