For the price - not worth it
To upgrade the front of my road king is 1600 for these calipers. Noticed ZERO difference than the stock calipers in good working condition. If these arent 100% aligned using the provided spacers then braking performance will be worse than stock.

Fit Perfect
Fit perfect on my 1994 Sportster. Super smooth braking with a new rotor.
