Experience absolute track-level cornering velocity and razor-sharp front-end precision on the open pavement with the high-performance Dunlop Sportmax Q5 Front Motorcycle Tire [MPN: 45247181]. Engineered as an extreme hyper-sport tire line, this premium front tire represents Dunlop's pinnacle high-performance street and track-day tire that requires no tire warmers. By utilizing specialized race-derived profile geometry and multi-compound technology directly evolved from MotoAmerica spec racing classes, it delivers a massive footprint, exceptionally rapid warm-up times, and unyielding pavement adhesion at extreme lean angles.
Part number 45247181 is manufactured in the industry-standard high-performance sportbike front configuration. Meticulously cross-referenced against factory assembly logs, this 120/70ZR17 front tire is a verified direct replacement fit for nearly all modern sport, naked, and superbike models, including:
CRITICAL COMPONENT MIXING, TEMPERATURE STRATIFICATION, AND PRESSURE WARNINGS:
**Strict Radial Track Geometry Warning:** The Sportmax Q5 is an extreme high-performance **Radial (ZR)** construction tire. It should **never** be mixed on a motorcycle with a rear bias-ply tire, and it cannot be used on heavy cruiser platforms designed for flat bias casing tracking loops. Mixing tire construction types will compromise chassis alignment and trigger severe high-speed geometry wallow.
**Cold Compound Glass-Transition Trait:** Because this hyper-sport compound relies heavily on high-tack carbon black race polymers, **the rubber compound can become brittle and fracture if flexed or hit hard under sub-freezing warehouse conditions (below 32°F / 0°C)**. Always allow cold tires to slowly warm up to standard room temperature (above 65°F / 18°C) for at least 24 hours prior to workshop mounting or tire iron stretching.
**Track Cold Pressure Calibration Logic:** When preparing this casing for track-day use, do not blindly set your cold tracking pressures to the motorcycle's street frame placard specs. Hyper-sport radial plies heat expand drastically; consult the trackside technician or use a dedicated tire pyrometer to establish accurate cold-to-hot pressure drops. Always execute the critical **100-mile highway tire break-in protocol** to strip factory mold-release glazes prior to dragging knees on local tracks.
