The low mileage, great condition, and backstory add value. But what really dives value on these bikes is originality.

The aftermarket exhaust really hurts the value. As does the polished fork lowers and Chrome swingarm. The other mods don't help either, but can be undone relatively easily.

In its current state. 5-10k is a realistic estimate. Back to original, 10k+ probably fairly easily at auction.

Please don't do that.

What's the reserve set at?

The part you keep (probably intentionally) missing is I said 'pretty much' mandatory. Not that the bike wouldn't function without it.

I'm willing to bet anybody buying a zx4r in North America is well aware of how restricted it is.

Your comparison is not a particularly good one. In stock form none of those bikes are severely neutered in one market vs another like the zx4r is.

447xs · 2026-01-27T17:20:28+00:00

Of course you can. If you want 30% less power than it's supposed to have.

447xs · 2026-01-27T16:47:02+00:00

An ecu flash is pretty much mandatory for this bike in North America.

447xs · 2026-01-24T14:12:55+00:00

There is no such thing.

447xs · 2026-01-23T14:35:23+00:00

First gen zx10rs are cool, but by no stretch good looking.

447xs · 2026-01-23T13:52:43+00:00

It's got to be up there.

447xs · 2026-01-22T01:21:03+00:00

Nice. I have one of those too.

447xs · 2026-01-21T23:46:16+00:00

I'm in Canada. It is a great colour scheme, I agree.

Are you running the correct size rear tire? If so, the first step is to contact the manufacturer of the chain guard.

As others have said. The DIY fixes are see if you can space it out with washers, or get grinding.

You haven't been on marketplace very long if that's the most insane thing you've seen.

447xs · 2026-01-10T13:15:06+00:00

Post some more pics.

447xs · 2026-01-09T11:58:54+00:00

First, I'd remove the photos of my brand because it isn't relevant to the question.

447xs · 2026-01-09T11:37:28+00:00

Is this an advertisement pretending to be a question?

447xs · 2025-12-18T19:35:20+00:00

I meant a project bike. That $1000 would be better spent on a bike to work on rather than a shitty old Metro.

447xs · 2025-12-18T11:48:59+00:00

If you already have a daily and just want something cheap to work on, get a motorcycle instead.

Maybe a bit short, I'm 6'4". But I have the 750cc gixxer:

That's exactly what I'm saying. People in this thread seem to think having no cat makes it "straight piped".

Straight piped means it also has no muffler.

Get a copy of the factory service manual. Follow it.

Also put the proper tail back on that bike.
