Michelin Bib-Mousse Front & Rear Combo - 90/90 21 - 140/80 18

With 7 MX World Championships, 22 Enduro World Champions and no less than 26 victories in the Dakar Rally-Raid since 1983 Michelin Bib Mousse has been tested and proven on multiple occasions since its creation!Specifically designed for use in off-road competition, Michelin Bib mousse is lighter than a Heavy Duty tube! When fitted MICHELIN Bib-mousse offers the equivalent inner tube pressure of 0.9 bar whilst at the same time removing the possibilities of having to retire from a race due to a puncture!This Bib Mousse is intended for speeds up to 80 mph (130 km/h) and should not be fitted to motorcycles for on-road use. Prolonged higher speeds can cause heat build-up and result in excessive wear and failure of the structural integrity of the Bib Mousse. Potentially resulting in injury to the rider.Each mousse is supplied with a tube of Bib Mousse Fitting Gel to make fitting much easier.Please note: Always follow installation instructions supplied.Size Options:90/90 21 - 140/80 18: Also fits 90/90-21 & 80/100-21 (Type M15) & 140/80-18 Desert Spec (Type M02)90/90 21 - 120/90 18: Also fits 90/90-21 & 80/100-21 (Type M15) & 110/100-18, 120/90-18 (2.15 - 2.50 Rim Size) & 140/80-18 (Type M14)90/100 21 - 140/80 18: Also fits 80/100-21*, 90/90-21 Desert Spec & 90/100-21 (Type M16) - 140/80-18 Desert Spec (Type M02)90/100 21 - 120/90 18: Also fits 80/100-21*, 90/90-21 Desert Spec & 90/100-21 (Type M16) - 110/100-18, 120/90-18 (2.15 - 2.50 Rim Size) & 140/80-18 (Type M14)90/90 21 - 110/90 19: Also fits 90/90-21 & 80/100-21 (Type M15) & 110/90-19 & 120/80-19 (Type M199)80/100 21 - 120/90 18: Also fits 90/90-21 & 80/100-21 (Type M15) & 100/100-18, 120/90-18 (1.85 - 2.15 Rim Size) & 110/100-18** (Type M18)80/100 21 - 110/90 19: Also fits 90/90-21 & 80/100-21 (Type M15) & 110/90-19 & 120/80-19 (Type M199)* To give a higher tyre pressure feel for experienced riders.
