MOTO-D "Pro-Series" Liquid-Filled Motorcycle Tire Gauge was designed because we were tired of always hearing our customers complain about inaccurate tire pressure gauges especially when this can cause loss of grip and premature tire wear. MOTO-D is Precision Accurate and Manufactured to European EN 837 Certified Class KL 1.6 Standards (1.6%) making it a Class Leader even versus gauges costing a lot more.
