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 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 inch wheel will keep your 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 inch 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.
04
Quality
The way we see it, it’s all in the details. We take much pride in our work, which shows in our finished product. When you ride with the best of the best, you ride with SMT. Forget cast, go with military aircraft-grade billet alloy!
05
Backed by a Lifetime Guarantee
SMT offers a lifetime structural warranty on our 21 inch motorcycle wheels. Your investment is protected because we have the highest standards in materials, testing, and construction techniques. You can be confident that your wheel will provide years of trouble-free performance.

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.
Do I need a new front fender for my 21 inch motorcycle wheel?
Maybe. If going from 16 inch to 21 inches, you may need a new fender for the much larger diameter. A fender spacer may be needed but look a little weird or rub 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-inch Fat Katz fenders come in Bulldog, classic, and wrap-around styles. They are made of steel and come unpainted.
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.
