I am going to put a Fastback tail on my Roadster. I know there are two different seats used on the Fastback. Is there one that may more closely fit my Roadster tank than the other? Cheaper to ask , ya think? I thank you all in advance. Don M
 
I have been playing with Commando's for over 30 years and it was not until I ordered a tail section that I learned there are 2 different Commando frames, I do not know when the change was but the rear loop widths are different.

Vinny, they say nothing good is easy! Too often I go ahead in reverse! Suppose my next step would be to see if my tail fits my frame, atta boy Donny! Thanks for you input. DonM

Does your mudguard loop have the bracket for the hand pump? I think it changed about 72 ish.

Is this a niche that somebody should fill?
I'm sure i could build a mold and make fastback tail sections for the late model frames.
But only if there was a market large enough to make it worth my effort.
 
How well do the fastback tail sections fit up against Roadster or Interstate seats.

Seen both these variations as custom mades, but must take a bit of glassing to make them look right ?
 
Checkout the Long Range Fastback seat available from Leighton in the UK.
It might be a close fit with a Roadster tank and you won't have to cut the knee pads off.

I bought one from Leighton years ago to fit with an Interstate tank and I had to trim an inch or so off the seat pan and then have the seat foam and cover trimmed to fit with the Interstate tank.

Also, Burton Bike Bits sells repo Fastback inner fenders.

hand pump?

Early Commandos (Fastbacks) had a bicycle-type hand pump as part of the tool kit, stowed beneath the seat/tailpiece, clipped to the frame in the usual bicycle manner.
 
This is a LR fastback seat pan paired with a HR fuel tank , I think the roadster tank is the same length for comparison?

This is the same pan with Interpol tank and a tailpiece that came from Ron Fratturelli ,don't know if it is original or pattern. But you can see it fits well.

While that addresses the widths of the seat frame rails....

Its the lengths of various seats, and tanks, that has not been addressed - anywhere ??
More info in this thread already than ever before ?
Now, if we could just assemble a table of tank lengths and seat lengths.

Naaaa, we are not that organised.....

I've seen various combos of various seats and tanks with fastback tailpieces that I wouldn't have thought possible.
Its obvious that owners are pretty good at having seats etc trimmed or altered to suit...

e.g. ?

A post here above has probably answered how this one is possible...

I have had a couple of seats padded to suit my own preference as the original seat construction by Norton has left me numb bum after only a few miles as does my T160. The custom seats do on the other hand allow me to cover many miles in total comfort and when I dismount the cycle I feel great.

I will not be buying a Corbin seat for my bat bike as I feel it might be a bit on the careless side after reading this magazine article .
