Title: 1991 K75s Handlebar tube size
Post by: andrew_Antoneypillai on July 20, 2021, 02:20:52 AM

All in, I have taken the old rubber handle grip off of my 1991 K75s. I would like to replace an aftermarket Handlegrip, can someone let me know what is the size of the Handlebar tube? I have a pair of grip which is 22mm and that will not fit over the tube.

Thanks for your help.

Welcome, Andrew! You haven't told us about your Brick. Does it have its original handlebar? Where did you get the grips that you are mounting?

When you buy a set of grips for a Brick, you buy a 22mm set because the BMW Brick handlebar tubing is 22mm in diameter. When you receive the set, the clutch lever-side grip will be 22mm in diameter; the throttle-side grip will be larger because it fits over the throttle tube which fits over the 22mm handlebar.

Often 22mm and 7/8" handlebars are advertised for sale as the same size; they are not.  A 7/8" handlebar is 0.225mm greater in diameter than a 22mm bar. To use a 22mm grip on it, the bar end diameter needs to be reduced to fit it.

I am so sorry, I got my brick about 3 weeks ago from Reading PA, it’s a 1991 K75s, has 75k on it. It came with all original parts. I try to slowly changing something to little more modern I guess.
She runs well, has a little oil leak that needs to be addressed.

Thank you so much you are correct, it worked.

I got this handlebar grip, https://www.amazon.com/gp/aw/d/B07C81S93N/ref=yo_ii_img?ie=UTF8&psc=1#immersive-view_1626833657708

I like the look of it and I can add a side view mirror as well.
