What weight are the BST wheels designed to carry?

Load rating of BST wheels.

BST has derived our load specification from experience in the field of motorcycle physics:

The load rating printed on the wheel sticker will reflect the maximum static load/weight that is permitted on the specific wheel to not exceed the critical loads during the dynamic situation of riding the motorcycle. We design with a safety factor of approximately 4.

To check if the wheels are appropriate for your bike you can use the following rules of thumb:

Scenario 1: Motorcycle with a rider:
The usual weight distribution here is approximately 40% for the front wheel and 60% for the rear wheel.

Total Static Weight or TSW = Weight of bike with all fluids + weight of rider = 220Kg + 90Kg = 310 Kg

This leaves us with the following load ratings:
For Front wheel = 310Kg x 40% = 124Kg
For Rear wheel = 310Kg x 60% = 186Kg

Scenario 2: Motorcycle with a rider and 1 passenger:
The usual weight distribution here is approximately 37.5% for the front wheel and 62.5% for the rear wheel.

TSW = Weight of bike with all fluids + weight of rider + weight of passenger =220Kg + 90Kg + 90Kg =400 Kg

This leaves us with the following load ratings:
For Front wheel = 400Kg x 37.5% = 150Kg
For Rear wheels = 310Kg x 62.5% = 250Kg
