Katana 1100 speer seat yoshimura exhaust

[busa ash]

So i have known about this bike in my mates collection for a while , i wanted it as its super clean and has the period modifications , speer seat unit yoshimura exhaust and a telefix fork brace . This bike is an import and on the nova system so plan is to replace the perished fuel pipe and fit a new battery as this was a running bike last year , get it motd and then a uk registration

ive got that same exhaust but its on my 750 atm.

That would definitely benefit from a proper exhaust and factory seat cowl while you're doing the mot and uk import stuff

To go back to standard seat and cowl you need to reinstate the rear frame rails as they are chopped to fit the Speer seat, it was the reason I did not fit one to mine in the late 80's when I had the chance of one on the cheap

Correct i was going to re fit the standard rear from my other katana 1100, but when i saw what was involved i am going to give it a miss

[Joseph]

The fact that it requires hacking up the subframe is indeed unfortunate 

[busa ash]

But as this was done in the 1980s i have no control over this , finding a katana subframe is a touch harder than a standard seat and seat plastics as they are available 

[neilw]

Oddly enough over the years I have seen a few sets of cut Katana frame rails for sale on Eblag.de. Presumably removed to fit Speer seats

[Joseph]

And it's not that complicated a piece of metal either. Just 4 tabs for the seat plastic and one bridge thingy at the back for the seat lock.

But that eFag tip sounds good indeed. Many german Katanas were massacred

when i did fitted katana bodywork to my inazuma frame i had to make up the rear frame to fit the tail unit and seat lock.  wasn't hard and doesn't need to be factory spec.

update pictures coming .....

Updated back to 80s . Still looking for an original seat base and foam to get recovered . This has been done by previous owner to a good standard but it need to go on my resto mod version in martini colours .

 

Had an exhaust bracket over engineered but it's fine for the period yoshimura exhaust .

 

Last picture is with its mates in its home
