600 vs 750 vs 1000

[B_A_B]

ok this is mainly to do with sportsbikes/supersports but you can still tell me stuff based on the CCs so long as it`s relevant and doesn`t confuse me.

so far i`ve had a brief dabble with an rsvr1000 and now i`ve got a 600 supersports that i`m happy with.(i got rid of the rsvr coz i couldn`t handle it on the roads and it kept giving me too many scares).
I find the 600super very competent and tbh i can`t fault it for solo or "2-up" riding but i`ve got this nagging itch to try a 750 coz i think it`ll be the perfect balance between the 600/1000.

If you`ve got or had a 750sports...and you can make a comparison of it against 600s and 1000s can you tell me what you know.
The general concesus gives me the impression that all 3 engine sizes are basically the same in terms of performance in the real world....(but i can`t say i agree on that comparing the 600super to the rsvr)...so i`d like experienced views from "real world" riders about the pros,cons,and differences between the 3 classes..

I suppose my main question is "what`s the difference between a 600 and a 750".....(apart from the obvious 150cc).

cheers for any replies.

Hi

Thing about the litre twins is that they are fairly lazy engines. Capable of producing much of their performance without that much effort. Performance wise they should be pretty similar to the 750 4s, not the litre 4s.

While pushed seriously there is not a massive differene between the 600s and the litre bikes in ultimate performance, the litre bikes are faster with a decent rider, and (like the litre V twins) easy to go faster on without needing the skills to keep it on the boil all the time.

All the best

The difference between my GSXR750 and my mates GSXR600 is the fat-ish midrange and a much much harder top end, although if the rider on the 600 gets the jump on you then its not a case of "oot ma way wee man".

750 is a more powerful 600, not a less powerful 1000. And you need to ride it that way.

The difference between by hornet 600 and the 02 RSV that I had was that the mille made doing stupid speeds far too easy, it had the brakes and handling to cope with it and I could use it well on the road, but I was going to get done for doing stupid speeds. As it was I only picked up 3 points, but that bike was the kick up the arse I needed to start racing. Still love it though.

I've gone from a SRAD 600 to a K5 750 - on the 600 i was always dancing through the gearbox because the bike had to be in the right gear and in the right rev-range to make 'good progress'.

On the 750 i can be a little more lazy and still get good drive, but still get that lovely high-reving rush.

In comparison with the handful of rides i've had on borrowed K-series 1000s, you can be as lazy as you like and still make alarmingly rapid progress - getting up to the higher revs brings the horizon much closer, much more quickly!

I love the 750, for me it's ideal - i love to thrash an engine (and there is something about gixers that seems to provoke me to thrash them!), but i like to be able to sometimes ride without having to thrash it everywhere. Personally, i feel the thous are too much for me, it's just too easy to reach custodial sentence speeds without much 'work' - i saw 180 on the clocks last time i rode one(K5 model), and it felt like there was a lot still to come (186mph restriction aside).

There have been a few occasions where GSXR600 riders have noticed the difference when I've been on the VFR750. By the frequency of the mirror checks, I'd surmise that the Suzuki riders were trying pretty hard too. Funny, because I wasn't really pushing it on either occasion.

I think it's because it is easier to keep the 750 on the boil. The GSXR theoretically has a significant advantage in both power and weight but the paper performance doesn't seem to translate to being useable road performance so well.

Exit a corner in the wrong gear on the 750 and it doesn't make such a difference, it'll pick up anyway. A good rider on a GSXR600 should make mincemeat of the VFR.

What about a 636

I love my K5 750. I never really got on with a 600 - too revvya ll the time, including the 636, although the 675 Daytona felt nice on a test ride.

As mentioned its more like a more powerful 600, allowing you to thrash the bike but also if you feel like it you can be a bit lazy with the box and still enjoy the ride.

And whilst its not really close to modern litre bikes in terms of power, its worth noting that the recent 750's have about the same power as as a 2001 R1 and weight a fair bit less, so they're not exactly low on power.

ive had a zx6r which had to be high in the rev range for it to motor along but very flickable i then progressed to a zx9r which was good for motorway cruising but felt heavy on twist A & B roads but was easy to go fast with lots of low down grunt i now have a gsxr 750 k5 which has the extra grunt so you dont have to rag it everywhere and flickable for the twisty A&B roads it depends what you want from your bike try and test ride one to see if it suits your riding style

[B_A_B]

Cheers for the replies.
I`m liking what i`m hearing about the 750 IL4s but the only problem is i don`t want a gixxer.Are there any others?

There`s another bike that caught my eye a few months back...the daytona 675.
What can i expect from a 3 cylinder 675cc compared to a 600 IL4??
More punch..or not?

It`s not that i dont like the bikes (well actually i hate the headlight unit but that`s another story)..it`s just that they`re common as muck round my way and there`s millions of them.
If i got a gixxer i`d need to spend about 700notes on a paintjob just to have something a bit different.

I`d rather have an mv agusta f4s over a gixxer though...no question....but it`s seriously out of my price range.
....and there`s still no sign of the Aprilia RS750 which i thought was due for release early next year??... so i might have to move to a daytona when the time comes for a change coz there`s not many other choices..

Having had a GSXR600, 750 and a 1000 here's my 2 pennies worth:


600 is ideal for a first 'big bike.' Sometimes feels like it's going to cut out - but still fast as hell.

https://photos-f.ak.facebook.com/photos-ak-sctm/v204/84/7/549000056/n549000056_2369173_7300.jpg

750 is a big 600 but accelerates almost as well as the 1000. Sounds good with a decent can on it and the K4 Yellow/Black one looks the tits.

https://photos-056.ll.facebook.com/photos-ll-sctm/v204/84/7/549000056/n549000056_2359760_5508.jpg

1000 - you don't ride it - you pilot it. It's a beast. Fast as hell, accelerates like a missile. Beautiful ride.

You can't beat a GSXR.

[t121anf]

if only they'd follow the rest of the bikes and have a twin headlight setup....

i'd also like to hear from anyone who has ridden a Daytona 675 and GSXR750 K1 onwards.

insurance is about the same for me on these, GSXR is the cheaper option and faster, but i ahve wanted a 675 since they came out, talk about a rock and a hard place.

oh and am i wrong for not wanting any other 600? all i have read is you have to rev them hard to get the best, i want some lower down power too.

(oh i even checked out an R1, just for laughs, but insurance was silly, so thats a litre out of the question)

[Mr Nice Guy]

If you can afford it, the K4/5 750 is a better bike than the Y-K3. Better handling, more comfortable, faster and much superior brakes.

Actually, I think its better than the K6/7. The 6/7 handles better but the 4/5 engine is punchier, with the 6/7 being more top end orientated.

Only thing that puts me off the 675 is the physical size of it, it looks tiny, but apparently it has a really tall seat so maybe that helps. They sound effing fantastic though. I think they burn quite a bit of oil, although an owner might be able to say if this has been sorted by now?? Meant to be a face lifted model coming out next year, so prices might drop...

600's do lack power when you have tried something bigger...

but if all you've ridden are 600's, then they are nuts. Lots of fun though, working them hard is part of the fun.

the GSXR750 I'd say is much more fun than the 1000, not much in it top speed wise, and the 750 will fairly motor when you push it, but you can tell its working, whereas the thou feels like it has barely broken a sweat...

1000's are for posing. [/quote]

The benefits of a 750 over a 600 won't be too noticeble at low speeds, probably wont feel that much different at high speeds though you will actually be going faster. If your happy with the power output of a 600, consider test riding a 750 twin ducati. About the same peak power output, but more botton end grunt.

[strag]

The GSXR 1000 will leave the 750 standing on acceleration, example: me and a mate on a track day at Silverstone, we both have similar abilities and were together through the corners. Him on a K6 750 me on a K5 1000. We hit hanger straight together and I pretty much left him standing.

Same with a mate on his 2000 R1 at Mallory a few weeks ago, he said no way could he stay with me accelerating out of corners.

In real terms on the road there is naff all between them if the riders are of similar ability.
