That is just too damn spooky. 2 minutes ago I was stretched out on the floor trying to ease my back and having nothing better to ponder than why Sturmey Archer hub type gears (which are absolutely genius) were never scaled up for bigger applications.rodbargee wrote: Wed Aug 25, 2021 1:46 pm https://cybermotorcycle.com/marques/gal ... busera.htm

The Guzzi V8 (W8?) GP bike was only 500cc. (iirc)

That's an awful lot of metal for not a lot of cc. Must be somewhere on the limit for diminishing returns power/weight-wise. Perhaps it was a 'cos we can' exercise.

I used to work with a chap called 'Johnny' Johnson (they knew how to make nicknames back then). He had been a designer for Connaught. The boss was involved in a class of racing where cars were limited to 500cc engines. The Norton single was preferred.Count Steer wrote: Wed Aug 25, 2021 5:12 pm That's an awful lot of metal for not a lot of cc. Must be somewhere on the limit for diminishing returns power/weight-wise.

The hub gears were scaled up for motorcycles, in veteran days. http://www.go-faster.com/VeteranMotorcycleHubGears.htmlCount Steer wrote: Wed Aug 25, 2021 1:59 pm why Sturmey Archer hub type gears (which are absolutely genius) were never scaled up for bigger applications.

The Sturmey Archer “real gearbox” ended up as the Norton Gearbox.


https://classifieds.thebikeshed.cc/details/2790CARBON NEUTRAL HONDA HORNET £11950
For sale is this custom cafe racer based off of a 2005 Honda CB600F Hornet, named 'Cuckoo' after the infamous cuckoo wasp, that has taken over a year to build, and comes with some unique eco-friendly features as well as a lot of custom fabrication and parts.
Eco-friendly features:
It has a plant-based/animal-free cork leather seat (with a removable cowl for passengers) and hand grips made in collaboration with the fantastic guys at Corkor
The custom fuel tank badges and Quadlock phone mount were laser-cut out of second-hand aluminium off-cuts (spare material from the most eco-friendly metal available)
The decals on the motorbike and AGV Helmet were produced from spare off-cut PVC-free 3M vinyl
It has been calculated that this bike will produce just under 23 tonnes of Co2 over the course of 1,000,000 kilometres, so the builder has donated to a charity called Team Trees in order to help plant over 100 trees to offset this, essentially making the bike “carbon-neutral” for that distance

Made me think of this!

A what now?
