ALLEN ON THE BUILD

I like using KTM motorcycles as snowbikes for a reason. They are the easiest motorcycles to work on and have the most available snowbike-specific aftermarket products.

My bike is built as a dedicated snowbike. I do not switch it back to dirt.

It is built as an MTN.TOP Certified Snowbike. This is the snowbike recipe I find most functional, with all the right products I enjoy. It also has mild performance modifications that give it a more aggressive powerband.

These are the things that make my snowbike a more enjoyable machine.
