This handlebar grip is a little bit special! - It is a copy of the very unusual and rare John Bull racing type handlebar grip - identifiable by the rubber grip being fatter on the outer side, this being of the type fitted to some of the Works Norton bikes of the 1920's - 1930's. For 7/8" diameter handlebars.
I believe the intention of having the rubber fatter at the outer end was to help stop your hand slipping off downward sloping handlebars - particularly on tracks like Brooklands, and with the vibration of older bikes. When grasstrack racing many years ago, we used to wrap medical tape on the left handlebar with the outer end being thicker - similar to this, for the same reason.
As you can see in the accompanying photographs - if you look very closely as some photos of the Works Norton team in the 1930's and 1940's you will see they were fitted with this very unusual and distinctive handlebar grip on the left side. It was not practical to fit a similar grip on the throttle side - so they were normally fitted with standard 'parrallel' type on the throttle, which we also sell (either Item or See detail listing for more detail. Item is for left handlebar grip only
If truthful, the quality of the pattern and writing is not the crispest - because it has been made using an an original/used grip from the 1930's . . . but I am told by the original owner of the grip - that the original grip used for the mould originally came from that great Works racer - Stanley Woods, which I fully believe, as I know the supplier knew Stanley Woods well himself. Therefore, although not a cheap grip (these are handmade by a retired UK craftsman in small batchs, and are very time consuming to make), they are very unusual and rare - and if you find wear marks and slight imperfections in the mould . . . you will know they may have been made by one of the original TT legends, which should be a great story in itself when your mates are asking where you got the grip!
