01
Smooth Ride
One of the most common questions at SMT is whether or not upgrading to a 21 inch motorcycle wheel will sacrifice ride quality. The short answer is no – you can improve your ride quality when pairing high-quality SMT wheels with high-quality American Suspension components. Making your motorcycle look great and perform even better than it did with most factory wheels.
02
Rides Like a Cadillac
There are many benefits to having a larger wheel, but the biggest one is the increased Angular Momentum. The larger diameter 21" wheel will keep your Harley motorcycle more stable at higher speeds. Additionally, the extra weight of the 21 inch wheel will help to keep your bike planted on the road. So if you’re looking for a smoother ride and increased stability, a 21 Harley wheel will keep you straight as an arrow.
03
Appearance
A 21 inch motorcycle wheel is a popular upgrade from the smaller 16 to 18 inch OEM wheels that come standard on most Harleys, Indians, and Metrics. Not only does it give your motorcycle a more proportioned and aggressive stance, but it also makes the wheel the center point of your bike.

01
Do I need to rake a 21 inch motorcycle wheel?
Most models of Harley, Indian, and Metric motorcycles do not need the rake changed when upgrading to a 21-inch wheel. Give us a ring to consult if you have any questions about your make and model requirements.
02
Do I need a new front fender for my 21 inch motorcycle wheel?
Maybe. If going from 16 inch to 21 inch, you may need a new fender for the much larger diameter. A fender spacer may be needed but it looks a little weird or rubs on the fork when you hit a bump. A new 21-inch fender tucks your tire away and will complement the new wheel.
Our 21" Fat Katz fenders come in Bulldog (wide front), classic, and wrap-around styles. They are made of steel and come unpainted.
03
Do I need a caliper adapter for 13 inch rotors?
When upgrading to oversized 13 inch rotors, an SMT adapter kit is an essential piece of equipment. These adapter kits have everything you need to install 13 inch rotors on your motorcycle.
