Nope, meant nope. The geometry may work out the same, but the 50 profile is differant than the 55. You still have the beach ball shape with the 50. The 55 gains more contact as you increase lean and it falls in much easier. The gain isn't in the added height, it is in the profile.

Ah, I see what you are saying now. I thought you were arguing something you weren't

Yeesh!

Anyone running a 55 notice any loss of straight line stability at elevated speeds? As in the bike being twitchy? Seems like a benefit of the 55 would be getting the bike on the centerstand a little easier.

I just finished the Idaho STAR Precision Riding Clinic and one of the instructors used to have a C14. He suggested the 190/55 since throwing this beast around at low speeds is intense and (after two days) quite exhausting. My question is has anyone with a rear wheel hugger done the tire size change and did the 190/55 fit under the hugger? it looks like Revzilla has a good price and I can use my accrued Zilla bucks.

TIA...

It just occurred to me that a 55 rear tire would change the speedometer reading for the better I think. Our speedo's notoriously read fast. When my speedo shows 79 I am actually doing 75. With a taller rear tire the bike should be moving faster with the same drive shaft RPM. With a .42 increase in the radius I calculate about a 4% increase in speed at a given drive shaft RPM. Which should almost compensate for the speedo error. This is assuming the speedo works off the VSS on the drive shaft. Does it? Has anyone running 55's seen a more accurate speedometer?

that has been confirmed on many of our GPS's. But who cares about speedometer accuracy, the bike just handles better which lets me go faster in the turns (where it counts)

I just installed one (a PR3) on mine, and I thought it was going to hit the hugger, but it did not. Other brands of tires may be different though. If it is too close, you might be able to tweak the brackets a little, to get a little more clearance.

Thanks... That's what I was hoping to hear... Now to decide on the Pirelli Angle GT or the PR3s...

Only purchase the PR3's if a second best tire won't suffice

I changed after I read a review of the c14 on a website.

I have not noticed any change in seat height. I did notice a big difference in handling and cornering clearance. the bike wants to turn much easier and holds the lean angle without pressure on the bars. I also don't have the feeler pegs touch down even when two up. I have no unused edge rubber on the rear and just 1/8 or so on the front tire.

also the speedometer is closer to being correct.

the rear tire also seem to last a little longer, maybe 1000 miles better. my rear always wears out sooner than the front.

+1, except a slight difference in seat height.
I use a ZX14 seat which is a bit lower anyways. PR3's

stevewfl · « **Reply #31 on:** May 20, 2013, 01:37:04 PM »

seat height difference is only 42-50 MM. Not much.

but the difference in handling is HUGE

I'll let you know in a bit. Getting ready to put mine on this evening.

For shame Jim, for shame

Happy to report that there doesn't appear to be any clearance issues from the hugger bolts. The only bolt that is the closest is on the upper side of the left bracket. Back in the old days when these huggers were very new to us there was some talk of the hugger bolts being a bit long. The clearance looks about the same to me, though. If you are a bit worried you could add some washers to that top bolt which would move it away from the tire. My bike is still on the center stand as I'm still doing maintenance on it (last thing is bleed the rear brakes. Should get that done tonight, then I'll stand it up and take a look.

VJ... Great news! Now if I can just make up my mind... I have a pair of PR3s and Angel GTs in my shopping cart. Decisions... Decisions!

My GPS tells me the speedo is still about 3 mph over reality with these tires, at about 65 mph.

Concerning Gumby's avatar, I've finally found someone I want to ride with in the pillion position!

Angels of course

The gentle push that was needed!!!

I'm never been as conflicted picking tires as I just was. I even had the kids at Revzilla get both tires out and had them do a comparison... The PR3 is slightly taller and the tire is more triangular (in shape) than the Angel GT.

I know what I'll be doing over the long weekend...
