Forks too stiff? What about rear.

Hopefully looking to pick up a G5 at some point.

I heard from a suspension guy that the forks have overly stiff springs and the suspension is difficult to dial in without a spring change.

Is this still true if you're only racing the bike and (like me) weigh around 211 lbs?

Also is the rear shock any good for racing (unlike the G4 shock)?

Thanks.

I weigh 195-200 suited and other then taking a couple turns of compression out of the rear i didn't think it was bad at all.

Gen 5 rear shock is better than Gen 4 but like the man said, not for racing.

New fork internals and replace rear shock. Then there is all the other stuff you will need to do, enjoy )

I suppose if your last name is Marquez, Rea, Sykes.. Then ya.. You might not care for the crap stockers.. But for the rest of us mere mortals, you'd be surprised how good the 2016+ suspension really is. Kawi really set a new standard regarding stock suspension.. Watch E*ay and see how much they're getting for the new forks and how long they stay on the market. Not too much more and you can buy a set of Ohlins.. I know several local racers that have been converting their bikes over to the new Gen forks as well as building new bikes around the new Kawi forks.. Try it first, then make up your own mind.. Your weight class and your experience will grow. These springs most likely be perfect for you and track day's possibly even a race or two.

Just sayin..

front springs need to be stiffer than for your weight, rear spring will need an upgrade to your proper weight, front forks will need valves. are you racing to win, going for a #1 plate or $, or just having a good time? got a few grand to drop into it? if you're racing for fun, don't waste your money, just enjoy the stock setup. to push it, you need to upgrade it. doesn't matter what bike you're on.

Thanks for the comments.

I will use an aftermarket rear shock for now and see how I go before spending on the front.

The bike I'm looking at has Ktech springs sprung for my weight, so there is that.

Does anyone that races on a budget with the stock front suspension have any real world experience in use?

I have seen some competitive lap times from some that use stock, but I guess the real question is how hard they would have had to push to achieve them compared to say if they had used a quality cartridge kit.

Argh... When you honestly feel that this suspension is holding you back, thats when you might consider dropping the big dollars..

I talked to several respected (known racers) and suspension pro's.. Before deciding on my ZX. They're the ones who pointed out just how good the new stockers are. Which pushed me over to the ZX paddock.. Including the rear shock, although not as good as the front... Also from your post's.. It sounds as if You haven't even rode one yet let alone set up for you?? Might I suggest you try it first..

Don't waste time and money racing stock shock, a properly dialed aftermarket shock gives you grip, confidence, safety, tyre life, serviceability.
I think fork cartridges are needed if pace gets below 8s from lap record. Unlike with gen4 forks, the gen5 benefits from a piston kit (I know two slow racers who say that forks are perfect for them with Andreani kit).

Gen4 race: high spec.
Suzuki GSX1300R Hayabusa 2013: stock.
Kawasaki KX450F 2016: love it.

You're right I haven't...I haven't bought the gen 5 yet...I only sat on one the other day :) I'm just mentally adding up the signs for all the bits I might need, but there is a lot to do before that.

Can you ask them what they felt was wrong with the stock front units.

By the way, you quote the x seconds from lap record thing quite a bit, but I don't think that is that useful considering the wide variety of track configurations and riding styles that exist.

Case in point...James Ellison set the fastest ever two wheeled lap around Brands Hatch Indy circuit this year in British Superbikes, doing a 45.097s - crash.net.

Yet even rookies on stock 1000s are doing high 50s around there.
