New trials competition tire. The D803 was Geoff Aaron's 2005 National Trials Championship tire. Compliant carcass construction in the front tire delivers excellent traction. Rear D803 is engineered specifically to provide superior grip. Radial-design rear tire works great for off-road trail riding.

NEW profile adoption

Also the front + the rear renovate tire profile, optimizing the rigid balance of tread and the side wall. As impact from the road surface is absorbed pliantly with the adoption of the NEW profile which analyzed damping quality and the rally quality which are required from the tire as a second suspension thoroughly, at the stroke latter half being able to give moderate bounce, assisting the rider. In addition it improves grip power with the optimization of ground form, shows power, in capture of the harsh section such as attaching leprosy staircase of approach run.

Light weight conversion

By controlling the gauge distribution of the tire section finely, in comparison with item “D801” until recently, the front + the rear tire weight approximately 5% reduction. Light weight conversion of class top-level was achieved, control efficiency such as inclination cheapness of the important front and back wheel improved substantially with trial riding.

New compound adoption

From dry, adopting the new compound which under all conditions grip is made powerful from at the time of wet and low temperature to at the time of high temperature. Coupled with the ground form which is optimized by NEW profile, you show secure traction efficiency even in the condition.

Evolved directly from the D803, gives significantly improved performance to both professionals and trial enthusiasts.
