Tyres - can a wider rear Tyre fit on a diversion

[rio]

:Dis it poss to fit a wider rear Tyre on to the diversion rather than the standard one i have any help please

[biblebasher]

this is one thats come up many times before. best way is to find an fzr600 rear wheel. must be marked 4x18", 1991-1993 i think. fits straight on to all the other divvy bits. or just run a slightly wider tyre.

[rio]

thanks biblebasher, have you any ideas where to look for a tyre and how to read the tyres dimensions (what the numbers are for i know 18 is for it is just the 130/70 i don't.

You can fit a 150 rear tyre if you get that wheel - I know because I did the swap myself. My recommendation is stick with Bridgestone BT45 , and get 150/70-18 and 110/80-17. Whether it really improves handling is debatable, maybe a little bit more stable, but it does look a bit less anorexic. If you really want you could probably get some better/faster tyres but you will be limited by the narrow front wheel, which is a bit harder to find. Do not fit a 110/70-17, I did this and it makes the bike unstable at speed. A 120/60 or 120/70-17 would be even worse.

It is a straight swap but beware: the disc bolts will break off, so get new ones. It's just basic M8 allen bolts, 40mm long or thereabouts. Fit with tons of copperslip. The bearings in the new wheel should probably be replaced too.

TBH From your other posts it sounds like you are a real novice. Feel free to have a go at this stuff, but be aware it will always cost more than you think to change anything.

[rio]

thanks amorti the front is 110/80/17 already but the rear is 130/70/18 can't i just put a 150/70/18 tyre on the rim that i have or does the rim have to be wider and if it is that i need a wider rim what do you recommend as i have to take into consideration the brake disc lining up on the brake caliper and sprocket is there more than 1 other wheel

[amorti]

Dude, calm down.

First things first: A motorcycle must be safe. Do not dick about putting the wrong size tyres on a rim. Ever. It can only ever lead to handling and safety problems.

If you must have a wider rear tyre, you must get a 4x18" FZR600 rear wheel from about 1990. This is the only way. The rest of the info is above. It is a straight swap, the disc will line up and you can use your existing sprocket and sprocket carrier. Either buy one or don't buy one, you now have all the information to hand.

Actually you can go slightly wider on a bike with the same rim but I can't really see why you'd want to, and I certainly wouldn't, but I know people who have, not on a D6 though. It might look a little better but won't really improve performance.

Safety should be OK if the extra width does not impact anything else but you will be loading the tyre against the rim in a manner it wasn't designed for, depends if you ride like a loony or not. Remember if you fit a wider tyre to the rim you have made a modification and your insurance might not like it if you bin it.

[amorti]

If you fit a 150 on the normal Divvy rim, it will pinch it, so you will end up with a triangular profile tyre. So in the end it won't look much wider, and will probably have a smaller contact patch than the 130 did. Also, the profile will rob any stability. The divvy already tends to be a bit wobbly at high speeds, that change would make it worse. Also you would never be able to steer tight enough to use the full width of the tyre so it would look like you have massive chicken strips and ride like a gurl.

This is right but a shocking colour.

This might be right, email the seller and ask him to check if it's 3.5x18 or 4.00x18. In fact the pic shows fzr 400 1995 which should come with 160/60-17, so you get a much better choice of tyres that way on a 17" rim, but there's no guarantee it'll fit.

true amorti your right i'm getting ahead of myself. i don't think i want to go down to a 17" but the second wheel is more me (grey) and not the first (PINK) manythanks again

[vanseagal]

I fitted Avon Roadrider 150 tyre to the back against all warnings. No problems in any way. It looks better and feels more stable. I like the tyre a lot.

Here is info from Avon's website. It fits 3.5in rim.

Roadrider AM26 (rear) 150/70-17 69V RIM: 3.50 - 4.50

17" wheels are the "normal" size. 18" is a "funny" size and it limits the choice of tyres you can get.

Firstly, you have quoted for a 17" rim, come back with the right numbers and I might believe you. But it's still not a great idea, and will still pinch the tyre as above. I used a set of right-sized avon roadriders and hated them as they were too pointy-profiled, so that's only going to make it worse.

Meh, tyres is all personal choice, but you shouldn't mess with safety for looks.

[Deleted]

Amorti, don't want to argue as I haven't got a D6 but how can you say all profiles will be pinched ? As you say tyres are a personal choice so Vanseagal may well be enjoying the Avons (somebody has to) and they must fit or he wouldn't have them.

I agree you shouldn't compromise safety for looks.

[vanseagal]

Oops, my bad Amorti. Here is the correct info from Avon's website:

Roadrider AM26 (rear) 150/70-18 70V RIM:3.50 - 4.50.

I have used BT45 tyres with the original sizes but I prefer Avons.

[freska]

I have a 98 600 n and this fzr 400- 600 wheel you mentioned will fit any year 600 divvy? I can see both sides of the topic (safety/cosmetic), I love my XJ rolled it out of the show room all those years ago and she's still like new, but I gotta admit that boney back tyre looks kinda lost by todays standards, if I change the wheel /tyre it will be purely for cosmetic reasons... I like to think of it as a face lift.... or maybe even a boob job >.<

[freska]

damn my impetuosity on my last post question, I meant Performance/Cosmetic... just so you know I'm not a raving loon (although to some that's open for debate) choosing looks over safety.

[cam7777]

I wouldn't recommend fitting a different size other than specified.

In a situation of a bad crash, a vehicle inspector 'could' apportion blame due to using wrong size tyres which could compromise safety, if you don't tell your insurance company about this 'modification' you could find that any big claim may be questioned.

Pretty much my take on it from reply #8. Can't see why anyone would consider it. There are other bikes with wider tyres for reasonable money if you don't like the look of your D6.

[freska]

I would consider changing the wheel to have a wider back tyre because I love the bike but hate the arse end... I'll probably cut off the rear guard high, get a hugger over the wider tyre, as for other bikes, I have several, my beloved xj6n being the smallest of them, but however, still stands pround in my garage amongst the others =)

[freska]

pround? I made that word up to look clever =)

XJ6N you say...are they any good

[freska]

I bought it 11 years ago, wheeled it out of the show room, never had a problem with it, cheap, reliable, it's my Sunday bike for when I take the mrs out ( she's a bit nervous on my bigger ones) I love it, where I live is quite rural and riding down them country lanes makes me feel like I'm on the set of Heartbeat >.< ( I don't call it a D6 because it isn't.) It's an XJ 600 n (just to quell any predictable pedantism! LOL)

It is a straight swap but beware: the disc bolts will break off, so get new ones. It's just basic M8 allen bolts, 40mm long or thereabouts. Fit with tons of copperslip.

I have never had a disc fastener break on me, I'm constantly surprised by the amount of people that have this problem.
Maybe it's just because I'm so damn' Ossum.
As for the coppaslip....I wouldn't be using that on disc bolts
I always use threadlock - it lubes the thread, and also holds the buggers in there.
Be aware that if you apply *anything* like copper grease, loctite etc, that the torque figure you see in the manual should not be used.The threads in the hub are aluminium, and easy to strip - they have a low torque figure for a dry thread, so you could easily ruin the thread by torqueing to the same figure with a lubricated thread.
I don't use a torque wrench on them, myself.

All that stuff about copper grease is true, and does mean my advice should be taken carefully. But Yamaha used thread lock, and that didn't want to give up at all after 10+ years (how often do you remove a rear disc anyway?), so I avoid it personally. On the rear disc I took off, I started out all careful-like, taking a plumber's torch to the bolt to be worked, for melting any threadlock. I put a well-fitting key-bit on a long ratchet, and started turning. Got about a 1/4 turn out, then back in, then out, then "TINK!" as it snapped. Oh well, try the next one... exact same routine. All in all, I snapped 5 of the bolts off with that method. The 6th one had to be drilled out. Luckily the wheel was going in the bin, I only wanted the disc for my wider rear with the serviceable tyre on it.
