How to Choose Technic Tires

Choose Technic tires by matching the model to your riding category first - sport/performance street, touring, off-road, or commercial van - before comparing sizes. Technic produces bias-ply motorcycle and specialty tires organized around application, so the model line determines the compound, tread design, and axle position before size enters the decision. Axle position (front vs. rear) is a hard constraint across the range: most Technic models are position-specific and are not interchangeable. Many touring and trail sizes are also Tube Type (TT), requiring an inner tube to function - confirm TT vs. tubeless (TL) before purchasing.

The model-to-use split: the Sport R and Stroker are summer performance fitments for spirited street riding; the Endurance and T&C serve touring and multi-condition riders prioritizing durability and wet-weather confidence; the Speed covers classic and cruiser rear positions; the ATV is purpose-built for off-road use; and the T-700 sits outside the motorcycle segment entirely as a highway-terrain all-season tire for commercial vans. Always verify size against your bike's owner manual or OEM tire placard - model year alone is not sufficient.

Popular Technic Tire Sizes by Model

The most common Technic tire sizes include:

• 110/70-16 & 110/70-17 (Sport R - front) - metric front fitments for small- and mid-displacement sport bikes; bias-ply construction, summer compound, S speed rating (up to 112 mph). The 110/70-17 is among the most widely stocked Technic front sizes.
• 140/70-17 (Stroker & Sport - rear) - performance rear size for mid-displacement naked and sport bikes; directional tread with rounded shoulders for cornering. Available in both the Stroker (high-performance) and Sport (everyday performance) variants.
• 120/90-17 (T&C - rear) - taller-profile touring rear fitment; TT construction, summer compound tuned for wet and dry traction. Common on commuter and standard-class motorcycles with 17-inch rims.
• 120/80-18 & 90/90-21 (Endurance & T&C Plus) - touring sizes spanning 18- and 21-inch rim diameters; the 90/90-21 TT is a widely used front fitment for dual-sport and trail bikes, while the 120/80-18 covers larger touring rear positions.
• 90/90-18 (Speed - rear) - classic and cruiser rear size with a high-profile sidewall; P speed rating, bias-ply construction. Common on cruisers and standard bikes with 18-inch rear rims.
• 5.6-15 & 7.35-14 (T-700 - commercial van) - inch-format sizes for light commercial vans; all-season compound, bias-ply construction, load-rated for cargo duty. These are not motorcycle sizes and belong to a separate product line within the Technic catalog.

Technic's catalog uses bias-ply construction throughout, which suits lower-to-mid speed applications and classic or retro platforms well but is not a direct substitute for radial tires on bikes that specify radial fitments. Speed ratings - S (112 mph), H (130 mph), and P (93 mph) - vary by model and must meet or exceed your vehicle manufacturer's minimum requirement.
