Tire width and performance (front)

[Half-Caf]

Hey guys, I'm getting some new tires and thought I would ask ya'll for opinions.
I had a 100/90/19 kenda in the front which I am thinking of replacing with a 110/90/19 shinko.
I am not worried about the fit as I will be running wider forks off of a CBR sport bike, but I was wondering how a wider front tire would affect the handling/grip/cornering, etc.

What are your thoughts?

This is a complicated question.  Manufactures spend a lot of time testing for the best handling using different size rims and tires. Having said that (and I'm sure there is someone here who know more than me) my opinion is if you put a larger tire on the front it will make your bike steer slower and not want to go around a corner. Going bigger on the back will also act in slowing the lean of the bike. I would stay as close as possible to what the stock setting is.  You could go up a size in the back and probably not have any issues.  But is you want quick and stable handling, stick with stock settings.

I use that exact tire on my cb and it has worked well for me. I would use it but my concern on your bike would be fender clearance. A 110 will be taller, how much room do you currently have under the fender?
If you check the owners manual, it should list the stock sizes.

Are you referring to just the model, or the size as well?
I haven't even mounted my wheels up yet, but as I am using a CBR front end, pretty much anything I do will be custom (including the fender brackets)

What rim are you using then? Go by whatever the rim size is.
I used the 712 tires on my 78k.

I will be using my 19" comstars ('80 cb750f).
Apparently the stock sizing for the CBR is 120/60/17 -what a mutt I am making

I agree.  When I got my new rear tire, I went down (thinner) to stock size and my bike now leans easier which makes for easier turning.  The grip is fine.

Last time I visited the Harley dealership, I noticed how the remade 47 has a huge, balloon-like, front tire.  I'm guessing it turns about as easily as an 18-wheeler

You are kinda in uncharted territory and at home base at the same time. Stock sizes work best on a stock bike,but yours is modified(uncharted territory),yet it retains the same wheelbase,rake and basic weight distribution of stock(home base). Tough call,really. I went down to stock tire sizes on mine. I miss how full my front fender was with the 110 now that has the 100 in there,but the handling difference was not subtle. Stock sizes really made a difference. Of course,it could also be the difference between my old H-D style kicks vs. the current Shinko's. But for sure,the skinnier tire feels like it WANTS to lean vs. the wider one where i had to push the bike over. But the wide tire wasnt at all terrible to ride.

For what it's worth,being someone who has run both skinny and wide,On my Buffalo I plan to stay with stock sizes from here on.But on HaCkJoB I plan to run the fattest/tallest tire I can get to sit on the rim correctly.
