katana or slingshot

[little intruder]

can someone clear this up for me got this bike as a sling shot but people are saying its a katana, whos right. rear plastics are off kat , swing arm of kat, front forks off kat all1992 , frame and engine off slingshot (gzx750f )


can anyone verify.

My understanding was the slingshot was just the type of engine, not the bike itself

I the slingshot was referring to the carb design of the old late 80's GSX-Rs, as slingshot describes the cross section of the semi-flat slide carbs.
But from what it looks like you've got yourself a tarted up post-98 F streetfighter.

Looks like a street fightered Kat to me... Kinda dig the front "fairing".

[little intruder]

"Slingshot" refers to the engine/carb setup for some 750 motors designed by suzuki in the mid 80s, and used into the early 90s. Primarily used as a performance boost for the GSXRs... as we all know, the (then) newly redesigned Katana borrowed heavily from the GSXRs powerplant.

"Katana" is a bit of americanized branding. Many many bikes are branded or named differently here in the US than other places. Most of the bikes sold that were GSXFs in europe and other parts of the world were never branded "Katana" at all.

That "branding" varied from country to country... So in the late 80s and early 90s, there were GSXFs that were equipted with the 750 "Slingshot" design motors. I have seen pictures of factory decals on european GSXFs with the "750 Slingshot" design on the tail sections. I believe these were done from 89-92.

As for the bike in question... this is what I can see from it...

It's definately a 89- 97 design GSXF frame, 750 model originally, heavily modified. The seats have been swapped (possible tail swap like I did?) to that of a 600, but the front footpeg bracket definatley gives it away as a 750 frame.

I believe technically that any 750 motor Suzuki fitted up with the "S1" stamped head was a "slingshot" powerplant. How much detuning on the cams they did still for the Kat engines I don't know specifically, but... That is one of the reasons that stamped head on the motor is so desired for engine mods. The slingshot motors were setup with different bore X strokes than that of the other motors at the time. I believe the typical setup was 70mm x 48.7mm and the slingshot setup was 73mm x 44.7mm. Due to the change, a redesign on the carbs were done as well for the GSXRs and so you had ram air tubes that forced air into the airbox where it turned 180 (slingshot effect) and was almost a forced air induction into the semi-flatside carbs (slingshot carbs).

Again, with the terminology.. a name many times gets atributed to many things.... so not only was the engine with the "S1" head called the "slingshot motor" but the carbs designed for high performance were also called the "Slingshot carbs"....

I do not believe the slingshot carbs were put on the GSXF slingshot motors, when installed in the GSXF frames, so you don't get the full "effect" of the design. Remember, the GSXF bikes are detuned for a smoother more touring performance.

the silver one is identical to the bike he modified ,even down to the colour, no s1 marking on heads

[RebornKat02]

I really dig it!!!

[loudnlow7484]

I believe the proper name for the Katana in the UK is the "teapot"

Thank you Kreylyn, I was unsure what differences there was. My DR750 is sometimes reffered to as a slingshot ???. The frame gives it away as a Kat , Teapot (UK). I like the look of Intruders bike , nice

If the head is stamped "S1", where would I find it. I recently picked up an '89 750 that was hiding inside some 600 body work and am trying to figure out exactly what I have.

Thanks

ya, that is a very cool "fairing" on the front!
