The original Tyre Pump for the CB92 is very difficult to find, it is also fitted to the C92 ,C71 and Yamaha YB1  etc. You can make a decent alternative using a BMW part. You will need to shorten the overall length, and re-paint, but it makes a very good alternative. Part number is  71 11  1 234 860 and costs about £20 pounds. The Rubber Cap is available in two colours and is found in our parts list.

The early Apollo version above is really the only one to have on a CB92.


See Apollo Pump instructions below with English translation.


Honda supplied an alternative pump universal part #(U72 - B005 08105 29600 SEE ABOVE) from the '80s but some owners have found this will not fit on in the original holders without modification. Some of these turn up on Ebay from time to time and make decent money but are to be avoided.



I use Super glue for cracks and if they are deep and still show on the outside I may stick sheet rubber to the inside and then use a black silicone to fill in the crack. Most of the restoration methods for a knee grip need to be done with it on a tank, probably not your newly painted show quality one! The thing to ensure is that it looks good from the outside, what’s going on underneath doesn’t matter. Cleaning is a critical phase warm soapy water is the only method I use, occasionally you can use the Safety solvent on stubborn stains, but I have know owners cause more damage with aggressive solvent on 40 year old rubber. The Sun is the biggest killer of CB92 Knee grips, remember that rubber loses is pliability as time goes on this is due to losing the solvents in the rubber compound. This process can be reversed slightly be putting the Knee grip in a box with an open tin of solvent probably cello use thinners, it must be monitored continuously as if forgotten about, you will end up with a sticky mess. Owners have commented that as cracks develop on the tank pad, they have used a inner-tube patch kit on the underside of the crack. and it seems to worked well.
