Knobby tires 50/50 are highly recommended.
High quality & strong hand guards to protect levers are recommended. We use and recommend HDB Ultimate Handguards.
Doubletake Mirrors help prevent damage to the expensive original parts.
Hard panniers are dangerous, heavy, and strongly discouraged during training. However soft luggage can remain on the bike.
If you’d like a bag to carry snacks & water in, a small backpack or camelbak is highly recommended. While learning body position through different drills, it’s most important to have the freedom to move around the bike as needed, so tank bags often get in the way.
