Bultaco Model 49 Sherpa, how many models.

[chappo]

I’ve just bought a Bultaco Sherpa Model 49 to renovate.

On searching for information on this model , which seems sparse people talk about different models of the 49.

Were there several models of the 49, what were the differences.

Top shock mount location moved down and forwards to where yours are during model 49.

Brake pedal design changed during model 49. Can't see yours.

Frame tubes under engine went from single middle tube to a smaller tube each side during model 49.

Outer engine casings design changed to your type during model 49. This co-incided with the frame tube change under the engine. This change was somewhere around number 2650. I don't have the book with me at the moment with the number in it to refer to.

Rear hub changed during model 49. Can't see yours well enough to say which one yours is.

Your lack of frame tubes under the engine is non-standard but is a common mod.

The book " Historia de la Sherpa T" by Francois Stauffacher is a good reference book for Sherpa T identification

A 1968 Bultaco photographed in 1970 with no mods. I think its a model 49 variant.

Thanks feetupfun. 
Sent images of the hub and rear brake.

But the frame number is 1787.

Yours has the later arrangement for the brake pedal pivot. The early arrangement had the pivot location to the rear of the frame upright.

Is your engine number also somewhere around 1787?

Your rear wheel looks like the early type hub (shared with model 10 and model 27)

Here are photos of my series 1 model 49 (49-00100) showing the early brake pedal pivot location (and brake pedal) and early type rear hub.

Thanks Pat, any views on the foot pegs, they look like those off a highboy frame. Or was that style standard on this 49.
