At DMG Motorsports, we present the Shinko 540 Series Rear Tire in 120/90-19 66M Bias TT (part #87-4314) — a purpose-built off-road tire engineered to conquer the softest, gnarliest terrain your ride can find. Whether you're churning through deep mud pits or blasting across loose sand dunes, this rear tire is designed to keep you moving forward with confidence. Shinko has been refining off-road tire technology since entering the motorcycle tire business, and the 540 Series reflects that expertise with a tread pattern built specifically for extreme soft-terrain conditions.

This tube-type (TT) rear tire is sized for 19-inch wheels and carries a 66M load/speed rating, making it a proven choice for off-road and dirt bike enthusiasts who demand serious traction when the ground gets loose. Its aggressive, self-cleaning tread design ensures the tire keeps biting into the terrain rather than clogging up and losing grip, giving riders the consistent performance needed to charge through the nastiest sections of a track or trail.

Features:

• Designed for extremely soft terrain, like mud and sand, with wide spaced knobs that shed mud quickly and a tall, aggressive tread pattern that provides increased traction in super soft terrain
• 4-ply high carbon compound construction for durability and long-lasting performance
• 120/90-19 size with Load Index 66 (up to 585 lb) and M speed-rating (up to 81 mph)
• Tube type mounting for authentic off-road fitment
• NHS (Not for Highway Service) — built exclusively for off-road use
• Outside diameter of 27.48 in. and width of 4.69 in.
