MotoGP to Adopt 17-inch Wheels in 2016

Monday, June 16, 2014
In early May 2014 Bridgestone announced it would step down as spec tire manufacturer for MotoGP, opening the door for Michelin to take over starting in 2016. The Grand Prix Commission has now confirmed that in addition to the manufacturer change, regulation wheel size will be altered as well, increasing from the current 16.5-inches to 17-inches. The announcement adds another layer to the series rule modifications planned for 2016, which also includes a move to spec ECU hardware and software across the board. The full FIM press release, which announces the rule update, is included below. – MotoUSA



The Grand Prix Commission, composed of Messrs. Carmelo Ezpeleta (Dorna, Chairman), Ignacio Verneda (FIM Executive Director, Sport), Herve Poncharal (IRTA) and Takanao Tsubouchi (MSMA) in the presence of Javier Alonso (Dorna) and Mike Trimby (IRTA, Secretary of the meeting), in a meeting held on 14 June 2014 in Montmelo, made the following decisions:

Technical Regulations
Effective 2016

Following the successful tender of Michelin to be the official MotoGP class tyre supplier it was agreed, at the request of Michelin, that the rim size from 2016 will be 17”. This required a change to the regulations which currently specify an exclusive rim size of 16.5”.

Postponement to Implementation of a Technical Regulation

Current regulations require all wheels to be homologated with effect from 2015. In the light of the regulation change above it was considered unfair to require teams to buy new, homologated wheels for 2015 and having to replace them with 17” wheels for 2016. The Commission agreed that the implementation of homologation requirements for the MotoGP class will be postponed until 2016.

The requirement for wheels for Moto3 and Moto 2 machines to be homologated from 2015 remains in place.
