Shinko 777 tires for my 2017 CB1100ex

Good point Flynrider.

Another thing to keep in mind with those Shinko sizes you mentioned is that they will be taller than the stock sizes. The front will be about 3/4" taller and the rear about 1/2" taller. Your speedometer will be off due to the taller rear tire.

hi Flynrider .. the front tire is my biggest concern.. I need clearance on that front fender.. 3/4 in. is about all there is with the stock tire..

Well, the front will be 3/4" greater in overall diameter, so the decrease in space between the wheel and the fender will be half of that.

that may buy me just enough room .. thanks..

hello again duck .. do you run spoked rims on your 2013 ? with that v rating I would assume they are tubeless tires .. I am hoping to find someone that may have installed a tubeless tire on a spoked rim with tubes..[/b]

Hi Chuckk,
I'm running the stock cast spoke rims. I don't have a 2017 rim to look at, but they are likely made by DID. I looked at an older DID rim and it did not have the inner bead shoulder like a tubeless cast wheels have.

I also looked at some newer Excel and Behr (OEM Triumph, BMW, KTM) rims, and they do have those bead shoulders. I suspect that a newer DID rim will have it also, but I;ll verify that. That inner bead would help a deflated tire, tubed or tubeless, stay on the bead.

I'm visiting Buchanan's on Wednesday, so I'll take a look. As far as the designations MT and WM, they denote different things. As I remember from the '70s, the MT stands for "motorcycle tubeless", and is cast in the sizing dimensions on all DOT street wheels that are meant as tubeless.

The WM (as in WM0, WM3, etc) designates a certain width of the rim on the inside, from bead-to-bead. As the number gets larger, the rim is wider. Buchanan's lists Excel rims from size WM1 to WM14. Buchanan Spokes - Excel Dimpled Aluminum Rims

To answer your question of whether you can run a tube with a tubeless tire, I have done that myself many times with no drawbacks. Some manufacturers do not designate a "tube-type" tire, instead they just say to use an inner tube with their tubeless tire in "tube-type" applications.

thanks again duck.. yes I have the MT markings on my rims, so I can run tubeless tires.. now I have been thinking about sealing off my spokes and running straight tubeless tires.. I have watched videos on the procedure, but I cannot seem to send the youtube link.. then one can use any tubeless tire without the worry of overheating or wearing out the tube.. although it seems you have proven that worry, not that big of a deal..[/b]

I am certainly no tire expert, and dread the day when it is time for a tire change on my 2017EX because of the limited alternatives to the stock Dunlops. Whereas the 2014 Deluxe, 2017EX, and later spoked wheels use an inner tube, all the other models have cast wheels with tubeless tires. In my reading/research while a tubeless tire can be mounted on a spoked wheel with inner tube, it results in undesirable friction inside the tire which generates equally undesirable heat inside the tire.

As a result I am reluctant to use anything other than a tire that is designed and intended to be used with an inner tube. Yes, there are tubless conversion kits available, but because the tires are the only thing between the bike and the road, I am reluctant to go that route as well.

Safety and regular maintenance is number one with me, so barring availability of a proper safe alternative, I will have to stay with the stock Dunlops. Perhaps there are members with more knowledge about this situation than I have that can shed more light on the situation.

Not completely true -- the 2014 Deluxe has cast wheels and tubeless tires. The OEM alternative to the Dunlop D205 is the Bridgestone BT54. Your shop can order them, plus they're available online.

Good catch LoneRanger, you are correct. My bad, dunno what I was thinkin, as the 2014 Deluxe wheels are definitely cast. I must be gettin old (er).

I have tried to copy and paste .. can't get it to work here on this site.. I did my search "sealing spoked motorcycle rims" .. maybe you, cormanus, have the magic touch.. to me I seems to be a simple solution to gain tire options.. some people may feel it is too risky.. I believe people should be made aware.. then they can make up their own minds.. now that I have found out I have the MT style rims on my 2017ex 1100, I will probably move forward and seal them.. it seems the biggest risk I would be taking is developing a slow leak.. posting the video will get people talking about pros and cons .. good luck ....................

The OEM tires are V-rated, and the Shinko 777s are H-rated. I've used Shinkos on smaller bikes and they seem okay, but on a big heavy, higher-powered bikes, I'd stay with a V-rated tire.

I replaced the tires on my 2013 in November with a V-Rated 150/70-18 Bridgestone BT45 rear. It was just $108.88 from Pardon Our Interruption. The front I used was a V-Rated 110/90-18 Bridgestone BT45 for $101.88. No tax and free shipping too. The Shinkos are just a little less.

The stock size is a lower profile, narrower size - 110/80-18. I would not recommend a larger 120/90-18 since it will make the bike steer much more sluggishly. It is effectively 2 sizes bigger.

Hello duck,
I just bought my 2017 ex and it came with a new Shinko 110/90 on the front and I have noticed every time I ride the front fender is covered with a fine black dust. I am wondering if the slightly larger tire is the cause or this is normal even with the 110/80?
Thanks,
Rossi

Sounds like it is rubbing somewhere. I suggest you go look closely before you have a tire failure.

jack up the front wheel a little and rotate the tire.. look and listen for rubbing ..

 

[GoldOxide_imp]

Had an over-sized rear tire once. Rubbing caused black soot and shavings. The rubbing tire wall side was also significantly warmer than the other side. Beware and take care [of it].

Hi Rossi,
I couldn't find any diameter specs on Shinko tires, but Bridgestone has specs on their popular front BT-45 tires:
110/80-18 - 630mm dia.
110/90-18 - 655mm dia.

So that's a difference 25mm, just shy of an inch, which means 1/2" closer to the fender, not figuring in the expansion from centrifugal force as the tire spins. Dimensions differ by brand, and even different models within the same brand, but this gives you an idea what could happen.

The black specs you are seeing may not be rubber dust, but more likely brake pad dust that is a very common complaint. Remember that it is abrasive material, so don't just wipe it off dry, use warm soapy water and a brush.

And Chuckk
A 120/90-18 - 673mm adds another 3/8" on top of that, so maybe 7/8" taller under the fender.

thanks duck, for the info.. that helps me with my tire choices.. right now I am still running the stock tires.. Rossi is the one with the immediate black dust problem.. I find Both of your comments helpful.. yours and Rossi's ..
now I am thinking about sealing my spoked rims and dumping those tubes .. Chuckk j.

I just replaced my front tire at 4000 miles with a exact copy of the original Bridgestone Battleaxe BT54. Why would you use anything other than what the engineers spec'd for your bike? They know best, and are way smarter than any of us blokes.

that is true.. they know best.. my reason for going just a little bit larger is only for looks.. I like wider tires.. what can I say.. if I can go just a wee bit larger front and rear without causing any disastrous affects why not.. I can appreciate the good handling of my little CB and don't want that to change.. if I notice any changes with larger tires, I will move back to stock sizes..

[Cormanus]

DBM, the very low mileage one gets on the BT54 from tyre is a good reason not to use them, at least in my opinion. However, I agreed that using the tyre size recommended by the manufacturer is a good plan. Except ... it’s been a real problem finding alternatives in the correct size.

I’m trying Bridgestone T31s at the moment, but I gather you can’t get the rear in the right size in the US. I simply can’t understand why, given the relative size of the markets, you can get a tyre in Australia that you can’t get in the US.

Cost of the OEM tires is something the Honda people have to think about when picking a tire for a bike like ours. When replacing your tire you might look for a better one even if they are more expensive.

 

[pekingduck]

Chuckk, both rims on the 2017 CB1100EX have inner bead lips similar to those on tubeless cast rims that may help retain the tire on the rim. Don't know that they are identical or will function the same, so proceed at your own risk.
