Thinking about a wider rear tire

[Tortuga_imp]

Right after I got the bike a guy was checking it out in front of Cycle Gear. He said it would look better with a 180 or 200 rear.at tire. Frankly I think he missed the point of the bike altogether. Its not supposed to be a super-sport.

This.

This.

160 is too wide for 4.25". A 150/70 is the largest size that can properly fit on our bike. If we don't care about how it handles and just care about the look, then at least do it right:

Again, we see people desperate to revert our bikes to a modern bike.

I don't get it Red, do you?

FOR THE LAST TIME. CB1000R's ARE AVAILABLE!

Well, I do get it from the POV that for some, the looks are what it's all about, but at least make sure you haven't messed up the handling to where you're gonna hurt yourself. Maybe that's another reason why this bike has a speed limiter; to account for crazy mods!

tire size as can be seen on the pic: 160/60
Kineo rim, assumably the only one available for the CB1100, a 4.25.


It give the rear a little bit more bulk, but nothing extreme or crazy as some call it here.

Ummm... my 2013 CB1100 is a modern bike...

In this old man's opinion, I think it's great to see people modifying and changing their bikes. Keep it up!

Sure, but if it's unsafe, I'll sound off. There's a right way and wrong way to go about changing to a wider tire. I went with one size up, the 150/70, which is approved by Bridgestone for the CB1100's rim size. Larger than that, we'll be changing the tire profile in a way that adversely affects handling. Moreover, the narrow rim is going to pinch the tire anyway, disallowing it's full width and proper performance.

We want to widen the rim to match the manufacturer's design specifications. Looking at the swingarm, I don't think anything more than a 160 could fit anyhow.

I couldn't agree more.

Really, this mans opinion is more radical than the modification discussed in this thread! LOL

The ppl here are just wondering about a wider rear tire, thats all.
I myself was wondering about a 160 rear, thats only 20 more than stock.
Its not like we are talking about a 180 or some fat dragster bike.

I repeat, there is nothing radical, extreme or crazy about considering a tire at that is a little bit wider than stock.

To the critics I ask, where is the limit for you to decide wich mod is good enough in your opinion and wich mod is considered extreme?

Tbh, I find the latest comments, witness of arrogance.
The start of this thread and those who are interested in this mod, me included, just want info about the possibilities, nothing more.
But the last few comments are waaay off topic and dont help anybody.

And for those who forgot, the CB1100 is a modern bike, with a classic look.
That doenst change the fact its still a modern bike.
But I dont read you guys critiquing Honda for giving the CB1100 an electric starter, fuel injection, digital information, dual disc front brakes, rear disc brakes, abs, linked abs, tubless tires, etc!

I can understand that comments that a wider than stock tire could change the handling, but the last few commants sound very judgmental, especially the one about changing it to a modern bike is ridiculous, the CB1100 being a modern bike to start with

That said, can we continue in the spirit of good collegues and CB1100 lovers and pick up the discussion where we left it (not that there was any feedback or relevant comment about it, buy hey, I keep hoping) with these wider rear tire

can it be safe to say that if you put a 150/70 on the stock rim wich is 4.00
that a 160/60 would be safe on a 4.25 rim?

A rim wich is made especially for the CB1100 from Kineo by the way...see the 2 pics above. Got them from autoscout, 2nd hand CB from France

Riko as I read this thread that is exactly what was being said, there is a right way to go with a bigger tire and a wrong way. The right way is to get a wider rim. The wrong way is to shoehorn too big of a tire onto a too narrow of a rim. At least that's how I read it.

To the best of my knowledge, on this forum, only Red Mist has tried a tire larger than the stock specified tire, so he is the only one that can speak with you on an experience basis.

You could also consider the classic BT 45 as it is available in the right dimensions. It is however NOT recommended by Bridgestone, so you'd run on your own risk.

The BT45 is a bias ply tire which is (I asked Bridgestone and got it as reply) totally NOT recommended for use on the CB 1100.
Meanwhile my dealer mounted Pirelli Sport Demons on my CB 1100 (both tires had enough profile left for another 6.000 km, but the front tire showed an extreme and unacceptable sawtooth pattern.

My first impressions after 600 km:
(+) The tires get faster and slightly higher warmed up which helps having a good grip.
(+) The tire falls much easier into the curve than my Dunlops. In the beginning it was a bit surprising, now I am used to it. They are more agile.
(+) Nonetheless, running straight forward (even with higher speed) is still stable.
(+) Correcting the drive line in curves needs a bit more "hands on" compared to my Dunnies.
(o) The profile design looks even a bit too modern for a classic bike like the CB 1100.
(o) No difference in grip compared to the Dunlops on dry road. (Wet roads not tested so far.)
(-) The Pirellis are a bit harder (or have stiffer flanks) so they are a bit less comfortable than my Dunnies. Maybe I will reduce tire pressure by 0,1 or 0,2 bar.
(-) The tires follow a bit more road ruts or markings.
