Morning all,
It's new tyre time and I've been looking around for what to get. Being 150/70 is not a common size these days there are few good pair deals.
120/70 and 160/60 is a common combination and I wonders if anyone has tried the slightly wider tyres on their xj?

Jr just had BT21's fitted at the correct sizes, I think he was £190 fitted.
I never tried 160's but don't see the problem, I doubt if you could go any bigger.
I'm sure someone who tried it will be along shortly.
We had actually asked for the contimotion price and were told the BT21 was in stock and only a little dearer. I like Conti's I have RA2's on the Bandit.

Yea I thought about the conti-motions, I have them fitted to my sv650 and think they are ok.
What I did find when touring was that they squared off a fair bit with the extra weight, and on the XJ I do mainly motorway miles so I was thinking a dual compound tyre would be better.
How many miles have you got out of the conti-motions?

I fitted a 160/60ZR17 Conti motion to an XJ900S without issue

I fitted a 160/60ZR17 Conti motion to an XJ900S without issue Conti motions may well fit, but in 180/55/17 size they are 20mm thinner than Avons at the supposedly same size, I had to trim the avons on the Breva as it was touching the swing arm, even though they are the correct size!

Thanks ori , I'll have a look at the gap between tyre and swingarm to see what kinda clearance there is currently.

Think the 160's are fine, issues were raised when a hugger was fitted iirc.

The 160/60 will, at least theoretically, have a smaller rolling radius (by nearly 10mm) than the 150/70, which will lower the gearing (and make the speedo read "fast").
According to my calculations the difference is 2.8% - not huge, roughly equivalent to one extra tooth on the rear sprocket (if the bike had chain drive, of course!) But since the D9 is generally considered to be a bit undergeared already, maybe not ideal.
Edit - the above calculations don't include the effect of squeezing the wider tyre onto the narrow rim, which would probably raise the profile a tad*.
*Technical term = a small positive value.

I didn't notice any change in engine RPM with the 160 fitted - 70mph @ 5000rpm

Bob,
Thanks for the input, are there any downsides to what you mentioned. Would the wider tyre on the narrower rim make the bike turn any differently? Same question to you from personal experience ori.
Looking at my current 150/70 pilot road, I have about 5mm clearance from what I can see, which doesn't leave a lot extra for a 160. That said I think the pilot road 3 is quite a wide 150 section tyre.
Seen some pirelli diablo stradas cheap in a 120/160 pair deal which I'm tempted to buy.

As HRHPenfold said, the conti-motions are a narrow tyre, didn't try with a 'normal' width 160.
To throw a spanner in the works, I have a Suzuki GSX750F with the same size tyres as the 900 (120/70ZR17 150/70ZR17) and bought and fitted some Nankang Rodiac dual compound tyres. I am really impressed so far. As you would expect, dry roads are fine, the revelation was that in the wet, they stick to the road like glue. I paid £110 for the pair and I am so impressed, I am ordering a set for my Fazer 1000. The Fazer currently has Pirelli Diablo Stradas fitted which are reasonable, but, like most Diablos, are showing signs of cracking.

In reply to Ori's observations on the Pirellis, I hated the Stradas on my Fazer 1000 - found them not grippy enough, especially in the dry when 'making progress'. They stepped out too often & I was glad to junk 'em. The Pirelli Sports, on the other hand, were great. I've not had problems with any cracking on them though, Sports or Stradas & I've used at least 8 sets of the Sports. I loved the Maxxis Touring on my D9 - brilliant wet or dry. Better than the much more expensive Pilot Road 3's I tried.

I tight about the maxxis touring, but I've read a few things that they don't last long I.e 4000 out of a rear?

That's the Touring tyre - I guess their Sports one is eaten more quickly, but I haven't tried them. I really didn't have any twitches on the Touring. They wore well too - when getting worn out the bike remained nice & stable, hands-off no-wobble, unlike reports on some other tyre choices (OK - I mean Bridgestones ).

Maxxis M6029 touring last ages with good grip, wet and dry. Martin, the Pirelli Diablo corsas which you fitted to the Fazer were showing signs of cracking within months, but you need to look closely my myopic friend

Couldn't go fast until I had fixed the problems introduced from the previous owner He managed OK . Back on topic: I wouldn't fit an oversize rear tyre. Correct size choices exist, budget & premium, & so I can see no advantages in fitting a bigger one.

Thanks for all the replies guys, m going to stick with standard sizes.
For those using the maxxis m6029 touring tyres, what mileage were / are you getting out of them and what is your typical riding?
I like the price of the maxxis (£107 delivered) but have read a few notes about rears lasting 3000 miles which would make them a false economy compared with some more expensive brand dual compound hoops.
