IRC Boken Plus

TRACTION & SPEED ON ANY SURFACE

The Boken+ is a multi-surface tire with a four part tread for smooth riding performance on any road. Boken+ tires are tubeless-ready, offering the flexibility to run with a tube or without. Running tubeless ready allows for lower pressures which provides better grip and faster rolling over rough surfaces, and a more comfortable ride.

The 650b size preserves the handling characteristics of your bike while giving you the tire volume to tackle any surface.
