Zx6r old school

Since I read this a few hours ago all I've done is look at these on auto trader, they're a bargain IMO!

F models are very good if you get a cheapo one, but suffer from horribly rusty exhausts, warpy discs and a high rate of rear suspension wear. Engines are very strong. Aluminium looky-likey steel frame. 120/60 front, 160/60 rear tyres.
G models are very different from the F. Although the engine is basically the same, the chassis is completely different, aluminium frame and better suspension. G1 and G2 are essentially the same, there are some very minor engine internal changes, but the only thing noticeable externally is the paint scheme. As standard 120/60 front and 170/60 rear tyres.
J models are still 600cc but have different pistons, cams and carb settings, and an extremely ugly twin headlamp fairing, (lights are very good though). Bit more power, uses more fuel though. Clip ons now mounted under the top yoke, but end up in the same place as they are offset upwards, forks an inch shorter, but very similar design. Same wheels as G models, but standard fitments are 120/65 front and 180/55 rear.
A model has 636cc engine, different carbs and some other internal engine changes, bit more power, loads more fuel, chassis same as J models. 120/70 front, 180/55 rear.
There is an H model, don't buy one - it's a very heavily restricted model that went to, (I think), Switzerland. Makes about 48bhp or something daft like that.
On all models now it is common to find a 120/70 on the front, and 180/55 rear as those are common supersport sizes. It doesn't really matter, there might be better edge grip with a 70 section on the front, but it will definitely turn faster with a 170 on the rear. 170s are getting rarer though.

If you do consider buying one, they are all so similar that I wouldn't fuss over which one to get, I'd just buy the best one I could find that suits the budget. Although they're one of the older models, G models are still very commonly found as they sold in larger numbers than the prior or subsequent models.

I had one,a J1 and it was a fine bike.Those Kwaks were both sporty and comfortable,something that went out with the later versions as fashions changed.I replaced it with one of the last ZX9s which was exactly the same,only more so.Still got it.

Yeah always loved them as a kid and really wanted one - probably because the stood out the most.
Have tried the new 600s as thought about buying brand new but they're just too small to do any miles on, and since I do the odd camping trip the 200mile tank range does sound enticing!

Phew... I thought I'd missed a problem with my A1P. I normally get 140 miles to reserve, and then get very twitchy about grabbing fuel after 160 ish. I didn't realise there'd be that much difference in the models.

'Tis true. Ridden only around town if it goes onto reserve at less than 175 miles it's time for some attention, as soon as you get out of town and on a run 200 miles to reserve is entirely achievable without great restraint. A track day can make that 85 miles though.

There is, I have a G1, Jambo has a J1, and TSM has an A1P, ridden side by side they both use notably more fuel than I do.

More fuel or is the tank bigger on yours.

One thing that was a pain in the 'arris on Grunty's G2, is that it was a complete and utter faff to get the bike stripped as there were more fasteners holding the fairings on than there are rivets on a jet plane.

Hoewever, you can't knock that build quality, it was very well put together so make sure you have plenty of plastics pots so you don't loose them all.

I renewed the fork oil, changed oil and filters, coolant and sparkies and it was without doubt the most awkward bike I've done it on. Not hard to do, just fiddly but it did mean I got to use all the universal joints and extension bars in my socket set which was nice

Good bikes,we have used one for endurance racing for 4 years now.I must admit it is far from standard but considering that every mile on it is 100% flat out very reliable.

As a side note a 675 Daytona outpulls it coming out of corners,only by fractions of a second but after 20 laps or so the time mounts up.This is not just over certain tracks but taken as an observation with 10 British tracks in the series.Coming 2nd out of 26 teams is a good yard stick.
Still a brilliant performer but will be getting changed for 675 triple this year.
