Hello fellow airheads

Usually these cost about £50 in the UK, but I was able to design and print in PETG. In my case it was able to handeling up to 200 Nm of torque.

This secures the final / bevel drive pinion gear, enabling torquing during removal or installation of the retaining nut on BMW motorcycle final / bevel drives. It is compatible with all post-1970 dual shock and Monolever configurations, excluding models equipped with Paralever suspension systems.

Should Fit:

• BMW /5 Series (69-70)
• BMW /6 (73-76)
• BMW R90S
• BMW /7 (76-84) - tested to 200Nm with PETG, 6 walls 25% infill.
• BMW R45/65 (78-84)
• BMW Monolever (85-96)
• BMW GS/ST (81-87)

Printed with PETG with 6 walls and 25% infill. Tested up to 200N on a 1977 R100/7.

Hello fellow Airhead fans.

I am busy getting my bike ready to ride after sitting for too long. Family has taken priority over time and money over the last decade. One item on my list of "To Dos" is the Gear Change Lever Sleeve which has perished.

I decided to design and 3D print one. It is originally designed for a 1978 BMW R100/7, but should fit:

• R60/6 | R75/6 | R90/6 | R90S | 1973 - 1976
• R60/7 | R75/7 | R80/7 | R100/7/T | R100S | 1976 - 1980
• R80 | R80RT | 1977 Onwards
• R100 | R100RT | R100RS | R100CS | 1976 Onwards
• R45 | R65 | R65LS | R65RT | 1978 Onwards
• R80g/s | R80ST | 1981 - 1987
• R80GS & PD | R80R & Mystic | 1988 Onwards
• R100GS & PD | R100R & Mystic | 1988 Onwards

Printed in TPU with 6 wall loops and 25% infill. It was a struggle to put on because the TPU is tougher than the original rubber. But I used a bit of motor oil (TPU doesn't react with motor oil) and was able to get it on the lever.
