Won't help any Norton boys will it!?

I've used the Triple Cycles 'semi close' conversion in several Triumph twins and triples and it makes for a really nice box.

It is possible to fit to a Norton using a Nourish shell, but it'd be a lot of work and cost, and as both Quaife and TT make good boxes, I'm not sure why anyone would bother!

Most of the guys in Australian historic racing who have old British shit heaps use Triumph 5 speed boxes, and there is even a side valve Indian here with one. I suggest the Phil Pick CR conversion for those guys would be good way of going quicker. A TTI CR five speeder costs around $5000. If I was fitting a Triumph box to a Norton, I would simply remake the engine plates and do what was necessary for chain alignment. Probably half the cost ?

If theres a Nourish Norton case for the 5 speed Triumph Gears , itd save the cost of a outrigger bearing . :x

You can mix'n'match Norton Gears . A old geezer had a wall full of differnt tooth numberd rust pre Commando gears .

Depends who you believe but Norton reported numerous material & a few tooth profile upgrades during the Commandos life .
Norton the smallest 1st that has the ( room for ) the Kickstart pawl mateing wotsits your lowest kickstart first. Unless you prefer jump starts .
You play around with a few teeth on a few of the other gears. and youve got a ' Semi Close ' . About even between Stock & Manx Ratios ,
which is all you need for the road . Thereabouts .

I think I did a silly thing when I bought the TTI 6 speeder. If I'd thought about it, I have se veral Norton Gearboxes with various first gears, and they are interchangeable. I could have used a standard commando first gear to heave the bike from a standstill during clutch starts. There would have been a bigger gap between first and second, however on our local circuit that would have occurred on a downhill slope, if the short circuit was used as it is for most historic races. Even on a flat circuit, it would be tolerable. After that, with the top three close gears, you never go below second gear and it is perfect everywhere . It would be a good arrangement eve n on a road bike, and t he cost is about $600.
This video shows the bit of the circuit at Winton Raceway where the start grid is positioned for historic races. It is uphill for a short distance then downhill for a long way where you can really fang it off the start if your bike can handle the second right hander. A lot of guys back off there at the start of races - I don't.

Now that's a sensation that can last a life time, especially on a clunker Norton engine.
