ZXR600 vs ZXR750 up to dec 95 for new era?

[varden]

So folks, plenty of you have had experience with the ZXR750, and hopefully the ZXR600 too...

So what are the pros and cons of these two options??

[gizmo]

So your thinking more about New era then?

[FrogZ]

Go the 750 mate....
Looking for a cheap ZX7R with "charecter" ??
I was hoping IT was eligible

[Smitty]

the early 7s were a better bike than the early 6s
..in just about every way

It only been recent (since the 7R finished) that Kwaka
has given the 6R extra grunt and refinement

hth

I would be seriously looking at a 93 -95 ZXR750 myself if i had a few $$ lying around to go race in new era. It's an awesome category for the budget racer!

Plus the poll results so far kinda say it all !

[Plaz]

That era it would be hard to find a bike to match the ZXR750, I still say to this day they have the best front end in the game.

[gizmo]

In the end, does it really matter?
They have different classes for the different capacities to race in anyways?

[Strika]

Have a little experience with this stuff.

An L1/2/3 ZXR750 is an awesome road bike. However to make a competitive productions racer from it will require a lot more work and money. They weigh a lot, and the motor is actually not that good in standard trim. They need heaps of set up $$$$ to make em go really quick. Triple clamps to get em to steer, the forks are low low rent jobbies and suffer from horrible hydraulic lock on high speed compression. Most guys junked em and put Ohlins or WP forks in them. They require a different link and rear end set up too. Spares are getting hard to find too. A mate of mine doesn't race his any more due to spare parts being thin on the ground and almost as exxie as new now.

Whereas the 95 ZX6R F1, is pretty simple to get going. Fork springs and a revalve, new rear shock, braided lines pipe jet kit go racing. Parts are easier to get and there are still lots of spares out there left over from old racers. (Get in now before new era riders snaffle all the good bits up.) They get around a race track (rider equality assumed) quicker than a proddy ZXR750 does. Yeah sure a full blown ZXR750 SBK will hose it, but then you're talking engine rebuilds a few times a season, or at the least one, but with SBK spec motors, they are not cheap to build. A ZX6 engine can be redone with stock parts on your dining room table. ( Yeah I did that when i was racing-I didn't have a work bench ) I just had a top and bottom end done on the racer, and it included some new parts like a starter clutch and some gearbox internals, as well as bearings, rods, pistons, rings, guides and seals, and a few other things for under 2K. A SBK spec motor will be 5K minimum for that, perhaps more.

Hope this helps.

Do tell me all about your ZX6 95model Strika, I'm getting interested in this new era racing & I reckon a ZX6 would be the go.
I thought I remember something aobut GSXR front brake calipers?
Is that legal in New Era?

Not legal for New era I don't think. I only use them for club racing. At the Vic Champs In Pre-Modern (the Vic Equivelent of New Era) I will run the std calipers.

My ZX6 is a little special so I can't tell all. It was originally built as Troy Bayliss bike for the 1995 season. I rode it in 1996 then pretty much retired and the bike is as it was raced then apart from a couple of minor things i have done recently. Here's a quick run down of what I am happy to tell.

Forks- Revalved and Resprung (all WP stuff).
Shock-Replaced WP.
Damper-WP.
Tacho-Scitzu.
Ram Air Pods-Carbon Fibre.
High tensile titanium and alluminium bolts.
Muzzy Titanium 4-1 race system.
Braided lines- Made by me.
ZX7R master Cylinder.
Cosway Carb Needles.
Race glass.
Valter Moto Rearsets.
Cosway Handlebars.
And a few other bits n pieces.

But really all you need is a shock,damper,fork revalve, braided lines and a pipe then you're away.

[Smitty]

hmmmmm
thought we were talking road bikes.........

[Strika]

Nah mate, New Era and Pre Modern are racing classes Smitty, Hence we are talking about racing motorcycles.

Mate thats just what i needed to hear!!

I'm only starting out so i'm not keen to spend the fortune that the ZXR750 sounds like it would need.

I just want a basic kit to get out there!

[gizmo]

Do they shotpeen & polish the rods on bikes?
What about balancing it all?
$2k sounds good to me for engine build.

[HemiDuty]

Wow very good info there Strika, I didn't realise that. Hence I voted for ZXR600 (there was no ZX6R option in the poll ).

So Varden, all you need to do is go back a decade in bikes and you should drop a bunch of seconds!
