My Honda CBF 250 has a linkage type gear change. There is a
bit of slop in the linkage. The reason
for the free play is that the joints in the linkage are just a bent rod into holes which tends
to wear. I thought I could improve the design. I bought a couple of 8mm rose
joints and these were simple to fit.
I got the rose joints from Engineers Mate via eBay for £3.26 each inc delivery ($5)

New gear lever arrangement |
*** update ***
This joint was first used on German aircraft in WW2. They
were later made by Rose Bearings Ltd in the UK & HG Heim Company in the US
where they are known as heim joints. My joints were made in China, of course.
I will try this on my cbf 250, as it will definitely improve the shoddy couplings thanks.
