K7 1000 vs L2 1000 (feelings engine differences)

Hi guys!!
Now I have K7 1000. I like it very much! But there was an opportunity to take GSX-R 1000 2012 as a new one with a 6k run at a very good price. There is a question: how much different are these motorcycles in dynamics with my K7? The engine for 2012 is more interesting? I will feel the difference? I'm interested in the engine and its difference with my K7

I have a 14 model and my son has a k6 his bike is more snappy where mine is a more smoother power but both really are as quick as each other just slight power delivery difference

K5-6 same bike great low end torque.
K7-8 same better top end less mid.
Unless you're just on street proving who's faster straight line. Any of these liter bikes are just fine.
Most people should focus on suspension.
A K7 with great suspension work will run off and hide on a twisty road or bumpy road on any stock suspension bike.
You cant use all that power on the street anyway unless you're running felony speeds and on the track, most all people cant use all the horsepower of a stock 1000.
Just my opinion. I ride both street and track.

Thanks for answers!

I'll ask the question a little differently: I'll feel the difference when I switch K7 to L2?
Or the dynamics is practically the same? it makes sense to change to L2?
This is the most important question fot me.

I think you'll find there are better options that will have a bigger impact in what you feel. Can't you just ride the L2?

Re: K7 1000 vs L2 1000 (feelings engine differences)

K7 looks way better than the L2 IMO. I have a K9 750 and I never though of getting a L1 as an upgrade...new gen Suzukis aren't anywhere near as good looking as those of the past, sadly.

Unless you're buying an L7 there's not much difference. Hence why Suzuki started falling behind in the first place.

I'd keep it

Re: K7 1000 vs L2 1000 (engine differences)

Everything after the K8 was unimpressive to me, and most of the world, especially with Kawasaki and BMW in a motorcycle arms race. Meanwhile, I have no idea what Suzuki was thinking. Saving money, perhaps? That's why is partially why I chose a K6: the S1000RR was way too much for a used bike, the K9+ did nothing for me, the Hondas burned oil, the 3rd gen ZX10R had no low-end and felt like it had 600 power delivery, and everyone had wrecked their K7/K8 (I was actually looking at one).
So, I think that if you're fine with the tech of the bike, stay with the K7. If you want a newer bike, the S1000RR and the 4th gen+ ZX10R are amazing bikes with big power jumps and technology bumps.

2006 GSXR "250" with an Akrapovic full exhaust and a flashed ECM. 162whp, 77ft-lb. Slow-lane certified
2000 Honda VTR 1000. Practically a 250.

Re: K7 1000 vs L2 1000 (engine differences)

I agree with all of the above.
I think S1000RR is the most armed and powerful bike among the 1000cc class. ZX10R 2016+ on the second place for me.
Italian bikes do not count (but I really like Ducati 1299s.Amazing bike and design!).

1299s vs S1000rr - it"s a holy war for me)))))

Re: K7 1000 vs L2 1000 (engine differences)

I definitely think the newer bikes are alot more refined, but that doesn't necessarily mean they are better.

Different people enjoy different things, the L2-L6 bikes feel super smooth, I think the smoothest of the bikes in that era. where the older GSXR are definitely just as fast if not faster, have a different power delivery.

As far as I am aware, the k5-6 best low end power, the k7-8 came out with a refined head, which lost it some of the low end the k5-6 had, but added some to the top. The k9-l6 has changed very little in terms of overall engine components and it seems from my experiences on riding later model GSXR's the Suzuki engineers worked on just making the power delivery smoother not more of it. Some dyno shootouts have put the k9+ as putting out less overall HP than the k7-8 which up until the L7, I believe it made the most power up top. The thing to remember is they had a lot less emission requirements also, which made them lighter (once exhaust was changed), and easier to get rid of the emission control units.

Re: K7 1000 vs L2 1000 (engine differences)

K9 to L4 had the chain adjuster recall, which Suzuki passed off as being associated with missed shifts and trying to recover by upshifting without disengaging the clutch. They never explained why this only happens to those years. I suspect that there's some sort of deficiency in the redesigned engine with repositioned transmission shafts that they don't want to fix.

the vendor that supplied the block used to soft aluminum. - pretty simple explanation

Re: K7 1000 vs L2 1000 (engine differences)

^I'd guessed as much when the recall first was mentioned. K5-L4 all came with the same blocks, 61445-40F20 RH/61446-40F10 LH. Yet the recall only applied to K9-L4. If the vendor happened to switch to a softer aluminum, they would only have had him switch back to the original formulation. But they instead used a different part, 61445-40F00 RH/61446-40F00 LH, and they are now the parts listed for all years. This sounds more like the new parts are stronger than the original design. They now list the new parts for all years because they fit and, by doing so, they don't have to keep both designs in inventory. But maybe I'm overthinking this.
