My apologizes, You are correct about the DOT 4" Rim, according to specification the 160-60-18 will run on a 3.5 to 5.0" rim with standard being 4.5"

I appreciate your comments, I have very limited track time (50+ sessions) at the novice/intermediate level on my 2011 GSX-R750 L2 and my CBR1000RR but enjoy the sport. There is always someone we can learn from if we keep in open mind. I appreciate your comments.
No need for any apology here; the whole thing hinged on the rim size. As long as Bridgestone says that tire'll work on a 4.00" rim, you have my vote. I didn't see anything on the Bridgestone website about tire fitment for the BT30 so I used the numbers for the BT45. I wonder if the BT30 is available in the USA...I know the larger sizes of BT54 are not.

50+ track sessions? That's not limited but of course you know that! Good on you mate, we all learned something today. Oh, just noticed and forgot to mention, we have the same bike, mine's a 2012 L2. Daytona yellow.

If you want "maximum lean angle" and a "large contact patch", you may be on the wrong bike. Michelin makes great tires but I haven't found anything they make that fits the CB well - yet.

And certain hazards, like tar snakes and gravel, will be a problem regardless of tire choice. They tar the roads like crazy in Ohio and my VFR slid horribly on those - maximum pucker factor. The viffer was also wearing Michelin Pilot Road 2 tires, which are great sport touring shoes.

Finally, the BT54s are not readily available, I'm finding. It will be awhile before I need to buy any, but sportbiketrackgear.com is the only place I have found both front and rear in stock. But I haven't searched that far and wide. It's surprising that the bigger web outlets like bikebandit and motorcycle-superstore don't stock these - or at least don't stock both front and rears.
+1, I have found the same thing, the BT54s are a little hard to find. I was able to track them down eventually but wound up doing the BT45V's. I liked the feel of the stock radials better but wanted a bit more width in the rear tire. The 150/70 works great but the bias-ply tires are not as compliant.

If these BT30's work out I'll be doing either those, or going back to the BT54s next time around. Word on the street seems to be the OEM Bridgestones are better tire than the Dunlops, which are unavailable except through the dealer as a Honda part, at very high cost.

Here's another bit: Bridgestone's website does show that the 160/60-18 BT54 will fit our bike as well. 4.00" is the lower limit for that tire. The BT54 radial in the 160/60 size is only 9mm wider than the 150/70 BT45, but the BT45 in the 150/70 is a full 20mm taller. That does make big difference in gearing. The 160 series tire is actually a tad shorter than the stock 140/70, but about 15mm wider. Here's a link to the T30 information. http://www.bridgestone.co.uk/moto/ranges/battlax/t30/

Check out this cool video of Rossi testing the T30...

When I checked them last night, I think they only had the fronts.

I thought the aspect ratio was better on the 160/60 than the 150/70 too, its closer to the 140/70's

Can't beat Revzilla, ordered these yesterday and arrived today.

I'll be doing some tooling early next week an try them out.

I found the T30s at:

They're cheap, 228 bucks for a set.

Looks just like mine, only black. Mine is also stock exhaust. Did you do anything to the brakes? I did the stainless lines and Galfer pads.

Red,
The only thing i did to mine is add a TRE from Ivans. It fools the bike into thinking its always in 4th gear to eliminate timing retard in gears 1-3, the only issue is your gear indicator always reads 4th.

If you want it I'll give it to you, i no longer have the bike, i removed it when i traded it in for the 1000RR.

Man, that is very generous of you! I'm thinking of having Guhl's reflash the bike soon which will also get rid of the timing retard so I plan on just leaving it alone for now, but thanks!

Heck I guess ridem32 is right, Nice Guys do ride CB1100s! And also GSX-Rs!Beer

RE: Tire Options for our CB1100
After 5.500 km the front tire (Dunlop) shows a strong "sawtooth" pattern with about 2 mm difference in height of the outer profile blocks. Sad Bad tire, sorry...
When my dealer will exchange the oil at 6.000 km in about 2 weeks he will also throw away these bad rim savers and replace it by Pirelli Sport Demon. The new BT tires in 160 dimension are too broad for me, I like more slim and agile rear tires.

The sawtooth pattern results in a "singing" or "howling" of the front tire when not riding straight. Additonally, there is also a little shimmy recognizable.

The rear tire is still fine, enough rubber for another 6.000 km or so. But the front tire is beyond good and evil. The Dunlop tires seem to be technology from the past century.
