Motorcycle Tire Pressure Chart: PSI / Bar Guide

Primary source: the chassis sticker

Makers print cold pressures on a swingarm, chain-guard, or door-style sticker. Web charts are references; your year sticker is the rule.

Measure cold (parked for hours). Adding air to a hot tire because it ‘looks low’ creates overinflation.

Typical cold ranges by segment

These are common bands, not model specs. If there is no sticker, use the manual; if a passenger / luggage line exists, use it.

• 125–160 scooters: front ~25–29 PSI (1.7–2.0 bar); rear ~28–33 PSI (1.9–2.3 bar)
• Naked / roadster 300–700: front ~32–36 PSI (2.2–2.5 bar); rear ~36–42 PSI (2.5–2.9 bar)
• Sport / supersport: front ~33–36 PSI; rear ~36–42 PSI (track setups differ)
• Adventure (street tires): front ~32–36 PSI; rear ~36–42 PSI; drop per maker / tire advice for dirt
• Two-up + luggage: many manuals add 2–4 PSI at the rear

Notes for popular classes

MT-07-class nakeds often land near ~2.25–2.5 bar front / ~2.5–2.9 bar rear from the factory; exact numbers are on the sticker.

PCX / NMAX-class scooters react quickly to pressure drift on small-diameter tires; weekly checks pay off in city use.

How wrong pressure shows up

Low: heavy steering, shoulder wear, heat, early tire death. High: center wear, harsh ride, narrower wet contact.

Routine and logging

Check at least monthly (and before long trips) with a digital gauge. Do not trust tired gas-station clocks.
