How to identify my model

[Target30]

blue dots bolt on to both 600 and 400 forks, except 89 600.

Sorry guys i feel like a idiot, my rotors measure 280mm, my mistake, gee and i build cabinets and measure stuff everyday, thats scary. Still dont know if those ones i want wll fit, im positive i have a 1wg, but its a 90, the ad says 89, so better stay away i guess.

Ok thanks for that, so i could still have 600 forks. Simple quetsion, how big mm are 90 400 front disc ?

As I mentioned earlier, I believe they are 280mm. I'd have to measure them to be absolutely sure though. The 600 rotors are definitely 298mm. Like I said, If you have 298mm rotors (and your stanchions are 38mm), you probably have 3HE 600 fork lowers. If you get a second, take a pic of the top triple clamp. I'll be able to tell the difference between the two. Keep in mind though that the triples could still be from a 400 since the 1WG 400 and 3HE 600 both utilize 38mm stanchions. Regarding the caliper boss spacing - The '90 1WG forks and '90+ 3HE 600s all used the same spacing (4-pot calipers). In fact, the '88 / '89 1WG and '89 3HE 600s also shared the same spacing (2-pot calipers).

Hey Rob,

Just to clarify, the '90 1WG 400 frames are the same as the '88 / '89 frames. That I'm aware of, the only differences between '88 / '89 and '90 are as follows:

'88 / '89
2-pot front calipers
box-style swingarm
red / white paint scheme

'90
4-pot front calipers
Deltabox swingarm
black / blue paint scheme

I think the 1WG and 2TK frames are the same though. I'm not 100% sure. The 3EN1 & 2 frames are different however. The main difference is that the sub-frame mounts a little bit farther back. Have a close look at the identifier page that I linked to earlier. There's actually a lot of good info there.

Mike, Do you own a camera buddy? LOL! Do you have 2-pot or 4-pot calipers? My apologies if I missed that info. Better yet, look at the rotors to see if the inner carrier is flat with the braking surface or offset. If they are flat, they are '88 / '89 rotors. If they have an offset, they are '90 rotors.

Brandon buddy, i dont have a camera right now sorry about that. I have 90 400 forks, 90 front rotors, 90 lower forks, im using blue dot calipers, its for 100% sure i have a 1WG 1990. Those disc i wanted in the Uk i now see wont work on my front end.

So is there anybody else making them besides EBC ?, sorry for all the confusion. I can get a camera from my neigbhor if i reallyyyyyy need it. So i just need a few options for rotors, i dont like having only 1 choice.

I know us rookies can be frustrating at times

It's all good. Don't sweat it. You have to remember that these bikes are pretty old so you're not going to find much of the newer bling aftermarket stuff. If you REALLY want fancy new rotors, throw a YZF or R6 front end on there. The YZF is very straight forward. The R6 requires a bit more work. May I ask why you need more than what's currently available? The rotors themselves aren't really adding much performance-wise. If you're going for looks (which isn't a bad thing), you're pretty much out of luck and would need to swap to a newer front end in order to take advantage of the current stock of aftermarket bits.

[Fzrmike33]

Well my stock ones that came with the bike are pretty wore out, darn near there wear limit, and i would like better looking ones i guess.

Well i just bought my blue dots, rebuilt my forks completely, so not ready for a front end swap. I guess i may have to go EBC if thats my only choice. I did find a very nice rear rotor for my bike, but the front ones are proving to be very hard to find.

Guess i could get some used stocks, but thats a gamble, cause unless you have the person selling them put a gauge and measure the thickness, your taking a chance of getting shot disc.

The guy is in the UK, he told me they will fit a 1990 fzr 400 1wg 3en2, i know i have a 1wg, is it a 3en2 that is to be determined ?????? i bet Roaddogma would know the answer to this.

This is what the seller said to me..............Dear califmike2003,

Hi, please check your chassis plate to see if it says FZR 400 1WG 3EN2, if so these will fit, thanks

Just an attempt to clarify this a bit more - When the sales guys says 1WG 3EN2, he's actually referring to what is colloquially referred to as the 3EN2. The 1WG "chassis range" probably refers to the frame style. The bike that is colloquially referred to as the 1WG (our 400s here in the U.S.) was the first bike to have that serial prefix (starting in 1986). Therefore, the prefix stuck for the duration of the use of that frame design. If you look at what we commonly call the 3TJ 400, you'll see that their "chassis range" prefix is 1TJ (yeah, I know - 1TJ - NOT 3TJ. Go figure...). It's a completely different prefix for a completely different chassis. However, the generic nomenclature 3TJ IS used for those bikes when referring to them as a whole.

In a nutshell, the 1WG style frame was used for the 1WG, 2TK, 3EN1, and 3EN2 models. Note that the 3EN models have different sub-frame mount points. The 1TJ style frame was used for the 3TJ1, 3TJ2, etc. models. Take a few minutes to look at the pics in that identifier. If nothing else, it will help you to understand a bit more what a lot of us are talking about (especially the guys overseas who were fortunate enough to get these other models - lucky bastards! ).

Ok thanks Brandon, they (UK) have all the cool bikes, 8 different FZRS, TZ 250s, 350s, Aprillas 250s, the list goes on, think im moving to London . Gosh and the prices some of those bikes sell for, there dirt cheap, of course they have boat loads of them over there, those bikes are like gold here, cost you a small fortune.

Brandon,

I was looking for that link myself to add some compairison notes. Some how I missed it from your post. The 2TK was kind of like the FZR400RR (pre SP days) with the single seat and adding the small adjustable items. But I had always heard the US 90 model was more desirable in the racing area for reasons beyond the swingarm. Something to do with the headstock welding area. Seems like the info I had heard was incorrect.

Mike, Yamaha used the same spacing for their caliper mounts. So all 4 pot calipers are swappable weather from a FZR 400, 600, YZF 600, R6, R1. Baring Radial mount of course.

Hi,
I seem to remember a thing called WIKI in which some bright spark listed a whole lot of inter changable bits for YAMAHA bikes BRAKE DISKS included. seems such a waste not to use such a useful reference :-}

Yeah, you're right about the 2TK having the upgraded suspension (fully adjustable shock, preload adjustable on the forks, not sure about damping on the front though). Our '88 - '90 400 frames are identical. I have a '90 myself and a couple buddies of mine both have '88s or '89s and there are no differences that I can see.

George,

The problem is that there is no mention of FZR400 rotors. I assume you're referring to this page:

http://www.fzronline.com/wiki/doku.php? ... her_models

If I can, I'll try to get some measurements so that the info can be added. If it's a different page, let me know and I'll dig it up.

Sorry Rob, I wasn't sure if you found the link or not. If you didn't see it, here is a direct link to the identifier page:

Yup that ref is the one
