The 18 inch rear wheel with the 300 tire has been the series standard tire
for every Boss Hoss since the manufacture year 2017. Basically, this rim
size fits for any Boss Hoss, but it could mean a bit more work to fit this rim
for older models manufactured before 2001. We differentiate between
models from 2010 on and before..
Suitable for all models from manufacture year 2001 onwards. Here, not
only the rim diameter is 2 inch larger than the standard rim, but also the
tire width is changed to 180mm instead of the standard 130mm.
For this, the mudguard brackets and front fenders must be adjusted.
Frontfender GFK/ Carbon
This fender is the standard front fender used in a conversion of the front wheel to 18 inches.
For mounting the fender holder must be adjusted. The material is 50% fiberglass and 50% carbon.
The 20-inch rear wheel not only offers enhanced optical aspects, but also
even more ground clearance compared to the series standard 15 or 18-inch rear wheel.
The tire size for this rim is 280/40 R20, which requires various
adjustments depending on the year of construction.
