FlatRacer BMW Airhead Boxer (post 1985) fork top nuts 41mm spanner tool EBM 111

FlatRacer BMW Airhead Boxer post 1985 fork top nuts 41mm spanner tool

FlatRacer BMW Airhead Boxer post 1985 fork top nuts 41mm spanner tool EBM 111

Designed and developed by us to enable secure and easy tightening and undoing of all the BMW Airhead Boxer 41mm fork top nuts usually fitted to the post 1985 BMW Monolever models. However, please check your bikes' size as some models were fitted with 36mm nuts (please see out other listing for the 36mm spanner).

Our heavy duty 41mm spanner tool is designed to be to provide the maximum contact area to these thin section nuts, something most spanners and sockets cannot do due to their chamfered edges. Our spanner provides a safe and optimised access to all the BMW 41mm nuts . 

The spanner measures circa 180mm in total length thus enabling it to be fitted in the original tool roll. Provision to fit a 1/2" drive breaker bar or torque wrench is provided, along with a small semi-circular cut out to enable it to be hanged centered on a tool wall/board.

This tool is made of heavy duty 6mm flat thick steel, developed with a flank drive so it does not damage the nuts' edges as force is applied to the centre section of the hex sides, not the corners.

IMPORTANT: Care should be exercised when handling as this is an heavy tool. Personal protection equipment is recommended when handling it (ie: gloves and steel toe cap shoes).
