Genuine Doherty throttle twist grip, as per those fitted to most norton models - including OHV and SOHC models.  We all sell a very nice reproduction item - but this is the real Doherty item, and has very nice crisp casting lines and genuine trademark as per originals.  This one is to fit standard 7/8" handlebar diameter

Update Sept 2022: Sorry but the price of these has risen again - but they are the genuine Doherty items.  FYI, we still have a handful of the steel bodied good quality (non Doherty) versions - Item 0345, almost as nice and very good value for money

Note - these genuine Doherty items are now manufactured with plastic grips - but if you look closely you will see that even that is tapered at the end the rubber grip slides on.  These are far more expensive than the other reproduction type we sell (Item 0345 - and actually those are very nice copies) . . . and although the difference between them is minimal,  this item has the important Doherty trademark cast into the top of the chrome casting, as original Norton items would have done - and a lot of customers (and also myself included) prefer to fit genuine branded items if possible.

Note also that these genuine 'Doherty' type twistgrips are not threaded where the cable fits into them and do not have an adjuster fitted.  The most normal method was to use a throttle cable which has the adjuster at one end of the cable already fitted - and with an adjuster nut on that adjuster, which meant the adjuster would slide into the hole on the twistgrip, until it reached the adjuster n\ut.  However - we also CNC manufacture a special 'Top Hat' type ferrule for this type of twistgrip - see Item 1178, that fits directly into the hole of this Doherty twistgrip - and allows a throttle cable with the adjuster in the middle of the cable to be used . . . as was available in period.  Note: see item lisitng 1178 for more detail on that ferrule - but if ordered at the same time as twistgrip, that item will be discounted. 

However, we also manufacture a special knurled cable adjuster (our Item 0871) which was of the type originally fitted to the Air Slide adjuster on Amal TT and RN carbs.  This adjuster and locknut is of 0.250" diameter and is also a good fit into the hole of these Doherty throttle twistgrips - so if you have a throttle cable without an adjuster fitted - this is an option - see attached photograph of one of our 0942 Doherty Twistgrips with an 0871 adjuster fitted

Norton twistgrip info:  In the 1948 Spare Parts Catalog the twistgrip of roadgoing singles and SOHC Manx models was shown as a different item - however, I have to say I cannot tell the difference between a Manx and a roadgoing model . . . they both look the same to me, and visually - just like the type we sell here
