K6 v K7 weight

Hi. Has anyone on here ever actually put the CAT on a set of scales ? Just curious as to the main bulk of weight difference between 06&07.

Re: K6 v K7 weight

The K6 is lighter, especially since the K7 has a dual exhaust.

Re: K6 v K7 weight

Did you do a search on exhausts and K7/K8 weight reduction? There are a number of threads on this very subject. Hope this helps

Re: K6 v K7 weight

I know the k6 is lighter. I've owned both models. I've searched various threads but no-one has actually put just the CAT on scales. I'm just curious as my K7 came without the CAT and I wondered what the weight was. People have guessed it's weight at around 20lbs on some threads.

I don't think my K6 felt any lighter than my K7 without CAT. I think the twin pipes make the K7 look heavier ( if that makes sense )

Re: K6 v K7 weight

There are some for sale on eBay, why not ask them how much it weighs?
I've seen 20 pound reductions for Taylor-made exhaust swaps (mufflers replaced and cat removed), but not 20 pounds for the catalytic converter alone.

Haha. I might try my luck asking an eBay seller.

Re: K6 v K7 weight

The CAT box weighs 3.75kg on it's own - I just measured it.

Re: K6 v K7 weight

Is it just an illusion that the k7/8 feel so much heavier than k5/6 then? With the cat removed there's not much between them. Not sure if the twin outlets or bodywork just make the bike look fat.

Re: K6 v K7 weight

Depends on the tires, the suspension, where the extra weight is located, if the rake is the same, etc.

Re: K6 v K7 weight

With the cat, exhaust valve cables and crap, it's about 10 pounds all told. The factory mufflers don't have much in them, no packing, just a couple baffles and a bit of pipe. They are lighter than they look but, obviously, all told, they'll weigh more than a single system, most likely. The K7 is still about a 450 pound bike with some fluids in so, it isn't svelte. The K6 is not really significantly lighter than this.

The K6 1000 weighs 435# full of fluids. I would say 15# is pretty significant.

Re: K6 v K7 weight

When reading the suzuki launch details for the k7 it seems that grams were shaved off bits and pieces so where does the excess weight come from. Is it only from cat and emissions junk?

Here are more accurate specs...

2006 Suzuki GSX-R1000 wet weight - 435#
2007 Suzuki GSX-R1000 wet weight - 466#

That is a 31# difference...

That's a big jump in weight. Surely emissions can't count for all that?

Re: K6 v K7 weight

No, I think the bike in general gained weight.

Re: K6 v K7 weight

^Other differences that may add weight: ISC, larger radiator, electronic steering damper, hydraulic clutch, 10 button rotors, projector high beam, protective cover on front of gas tank.

The service manual weights are K5/K6: 365 lb, K7/K8:379 lb. As I understand it, these weights are measured in a funny fashion, i.e. all "consumables" are removed. That means no gas, oil, coolant, brake fluid, or (I think) even brake pads. Not sure about fork fluid. But strangely the tires remain. So the weight values are a bit silly. But the weight difference ought to be meaningful.

As I was reading this I was sure that you wouldn't have mentioned the heavier projector type headlight but you proved me wrong. You don't mess with @BillV when it comes to specs...
