Hello,
I need some information about a 5 speed Albion gearbox (not the modern Enfield box), that was used on the 250 Greeves Silverstone race bike.
1) Are the internals exactly the same (interchangeable) as a 250 Royal Enfield GT Continental? In the pics that I have it looks a bit bigger maybe.
2) Can the internals be used in an Enfield Bullet (Albion) gearbox? I.e. 5 speed Enfield?
The reason I ask is that I'm building a diesel bike (954cc twin), I can't use a modern 5 speed Enfield box as they don't make the longer diesel main shaft for that box. Also alternative gear ratios are not available for the new box, and I need to change the ratio's to get into overdrive. I need an overdrive to get me to 90mph. I need 5 gears or town riding will be a nightmare.
I will also be setting the sprocket sizes accordingly to aid the top end.
If anyone has a Greeves 5 speed for sale please contact me.
Thanks for your help.
