FZS600 Tail conversion / Swaps (Sports bike grafted)?

[F4celess]

Have been considering Sports bike Tails for my Fazer, especially a couple of Ducati options.

However, perhaps unlike most other sports bikes, the Fazer doesn't have a detachable rear Subframe.
It's all one big welded frame (front to back) - assume which added to some of the cost savings during production.

So the existing frame would need to be cut at some point (something I'm extremely loathed to do), where the donor subframe would be welded on.

Anyone have a Fazer, where such a conversion has been carried out? Success stories? Considerations? PICS??

there are loads out there done - but never a quick easy swap
i built an entire subframe for my old fz600 from a spare i had laying around for a race seat from a midi moto
an option could be to use a bolt on subframe, weld on some attatchment lugs so it becomes a bolt on, you could play with its geometry easier that way
ie - weld on top lugs and bolt then figure out the dimensions of the lower lugs to get seat angle or eurofighter arse up look.
that might be the way i go but i havent decided yet as i can use the bits i need to chop off the standard sub to make my eurofighter seat fit

Hi Disorderlypunk, thanks for your response.

Perhaps I need to do a bit more digging, to find some examples on here.

Welding on lugs sounds an interesting idea. Then a bottom set, to take an existing Sport bike Subframe.
Although the width/spacing of an existing Subframe, isn't likely to be the same as the left/right sides of the Fazer rear frame (to line up straight off).

I'm thinking commit to a specific Sports bike tail, buy that Subframe complete (fleabay), then adapt the Fazer rear frame to suit, so ultimately the 4 Lugs welded on will then enable the new Subframe to bolt straight on (as you say). Will require an amount of trial and error. I don't have any welding skills/facilities, so I'd have to rely on a fabricator to complete. Do you do this sort of work? Any idea on how much its likely to cost?

I wouldn't want to go too Eurofighter, it doesn't suit our UK taste (so much) More just a seamless looking transition front to back, with a more aggressive/purposeful rear end.  8)

not a clue how much a fabricator would charge as i do my own welding
a cheap welder would give you the ability to tack on what you need (and grind off if wrong)
then could be sent to a fabricator to fully weld up which should look profesional


sometimes its best to have a subframe in your hand so you can see how things align and what methods could be used/bodged

found this pic check the subframe mounting- will be saving this into my bits and pieces folder and pintrest

had an 03 R1 put on mine by a local bike builder as my welding is shit

He there great idea. I've been looking into doing the same thing myself. I'm wanting to do a bolt on version too as I'm looking to put a cafe racer / bonneville style subframe and seat on mine for when the misses is riding pillion. And then have a solo race style seat that I can switch to when I'm having a blast on my own.


I've looked into this a bit and figured that if I build an entire seat unit with all electrics in place so I can unplug the lighting and unbolt the frame I should be able to switch and bolt on a new subframe and plug the new lighting in.


Although I'd do most of the work myself with a fabricator mate finishing off the welding. Is there any mot issues regarding strength that might arise ? How did it go with your r1 rear end ?

lol i put up a pic of wraiths bike -what are the odds

A "hot swappable" rear end.   Could devise a "universal" loom connector (coming from the bike), so both swappable tail sections (café racer / race) have an identical mating Connector (for lighting / indicators etc), and just plug straight into the bike. Could literally be a 5 minute job to swap tail sections. Both swappable rear subframes would have 4 mounting lugs of identical dimensions/positions, so they mate to the rear frame of the Bike, where corresponding lugs are welded on. This sounds a great idea!

There appears to be a good deal more going on there, including the rear Swingarm. Was that R1 also? Straight swap?
The rear now looks almost too "sporty" for the front Fazer (half) fairing? Very nicely finished.    8)

I'm quite surprised almost 20 on (from when the FZS Fazer came out), there's no aftermarket Seat options. So instead of the standard factory front/pillion combined seat, there's some kind of Hybrid option(s), that replaces the original seat. Perhaps moulded single Sports seat, and even rider + pillion however as 2 individual padded seats.

Exactly what I was thinking. Could even make the original tail u it subframe to match the new lugs so you could technically put it back to standard.

no MOT issues on mine all the suspension is from  a 2000 RSV MILLE . it  was not an easy job there are spacers on the frame that need removing + top hat spacers to machine for the swingarm and depending on your preference either the top or bottom shock mounts to modify as the MILLE shock is off set not central

after seeing your post over on the other forum i have been eyeing up mille parts alongside my other ideas possibilities i.e. single sided
-where did you get your airfilter setup at ?? - im just running shit chinese pods at moment till i find something better
if its easy its no fun !!!!!

that system has been scraped now as it looked shit now running the original air box inlets and RAM AIR SOCK FILTERS for a GSXR1000 looks a lot better ill post a pik a little later 

[wraith600]

wont accept my pix as there to big so i posted on my FB page https://www.facebook.com/mark.edwards.16...161&type=3

[Disorderlypunk]

will have to wait till the GF gets here as i dont have FB and cant remember her password lol

[Disorderlypunk]

did the r1 seat fit perfect flush up against the tank or did it need modding? - rather mod a r1 seat than create and entire one from scratch
yep they are the same ramairs i have my eye on - oval seems a better plan than round

[wraith600]

the seat fits good had to trim a small amount from the plastic underneath the hook on the front fits under the rear tank mount 

[Disorderlypunk]

trimming underside isnt a problem as it will be going on a flat race seat unit anyhow
i was struggling to figure out how to get a seatpad to sit nicely with the tank
-problem solved - cheers

I'm beginning to consider an R1 or R6 Swingarm as these are favourites for a Swingarm extension... going all out ! Would need to find a competent local bike fabricator.

Modifying the Swingarm to fit the Fazer would be the technical/difficult part... then the (tried and tested) extension Kits are simple to bolt on afterwards.

Am sure this route is fine living in the States, with mostly straight roads, however with our more "technical" twisty UK roads, such a setup could be more of a challenge to ride (losing some cornering agility?). FAT rear tyre.  :lol Perhaps I've been watching too much youtube!
