For those of you that have a 170 on the rear...

How much clearance between tire and swingarm?

Did you attach the rear drive to the wheel before mounting to the bike?

Does the fender rub on the tire if bottomed out?

Did gas mileage go down?

Is it worth it? (The extra cost)


Thanks,

DT

My bike came with one and whoever put it on cut the center support off from between the center stand legs. My guess was for clearance, but I don't know for sure.

My swing arm clearance was very slim; half inch maybe.

Getting the wheel in and out was either in two steps involving the drive unit like the Clymers spells out, or letting the air out of the tire.

It never bumped/rubbed my fender.

I didn't notice much difference in gas mileage or anything else between it and the 150 I replaced it with, though I never paid much attention to those things at that time either.

Worth it? I don't know. I'll leave that for others.....

I have the 170 in rear. love it. For one I put on Metzelers which have better handling anyhow, but it feels like it wants to lean into the corners much easier. I think it corrects the speedo slightly, so mileage doesn't really go down, its just more accurate. Not sure what you mean by "Did you attach the rear drive to the wheel before mounting to the bike?"
For clearance check out this thread, I took lots of pics

I did a write up here: http://www.vn750.com/forum/showthread.php?t=10229

Your gas mileage does not go down (as far as I can tell, it goes up slightly). Your RPMs at speed go down. I.e., whatever highway speed you get at 5k rpms, you'll get the same speed at 4.5k rpms.

I took off the final drive and fitted it to the wheel before mounting both to the drive shaft. It's easier to get the whole thing in there instead of trying to fit the tire to the final drive while it's still attached. It's only 4 bolts.

You may as well lube the splines while you're in there.

speedo is measured off the front tire so no matter what the rear is speedo doesn't change, the 110 90 19 in the front fixes the slight speedo inaccuracy...

Yeah this one I go around on with people. I know the speedo is measured by the front. But when you change the diameter of the rear tire, it is a kin to changeing the rear sproket on a chain drive. Its like changing gearing. So it changes the actual speed you are going.

I also run the 170 on my ride, no rubbing issues with the fender (even with lowering shocks) but I was getting rub from the center stand so I just took a large rubber stopper, drilled a hole through the middle and zip-tied it to the bottem of the swing arm to lower the stand enough to clear the tire.

Clearance of the swing arm is minimal but enough that theres no issues.

As for mounting the tire I leave the final drive in place and use a floor jack to raise the rear of the bike a little, doesnt take much, and slide the tire in from the rear.

As for being worth it (the extra cost) it was the same price as the stock 150, I went with the Kenda Cruz I am thinking the price was about $52. So yes, well worth it...LOL

Well you can go around with me on it since I have the 170 on the rear and the 100 on the front. I have the tour fender so I can't run the 110 on the front.
Consequently my rpms are down because of the "gearing" change on the rear but my speedo is still off.
With a 110 on the front I'd have (fairly) accurate speedo (5-10% correction) and lower rpms with the 170 (running 4.5k vs 5k rpms at speed)

Well since I put the 170 on the back, and I didn't change the front to the 110 cuz I wa stupid. I have had a more accurate speedo. taken some rides with the GPS and went through the speed traps. Now I said it is more accurate and slightly more accurate. It is not totally accurate. Whereas before I was 5mph now I am 2.5 to 3 mph off.

Where and when did you get a 170 for $52! Dam, I'll buy two for that price.

What's the diameter of a 170 vs 150 to make such a difference in RPM's at speed?

So for the cheap tires, what's the pecking order for IRC, Kenda, or Shinko's?

Of the cheap tires, what do your recommend?

I've used IRC on many bikes but I'm not getting much more than 5k miles on the rear.
I have Shinko on my GL500 and like them so far.
I've never even seen a Kenda Kruz.

Only changes the rpm's at the same speed. Tach difference, not speedo.

I gotcha now, well I went with the Kenda Kruz's last spring and have been riding everyday this past year (with the exception of 5 days of snow). Putting over 8k miles on them, and still have a ton of tread left on both. Will probably have to buy new ones at the begining of next riding season. So averaging it out, I am expecting to get 16 maybe 20K miles on my set.

That's some great mileage on those tires.

I just found out the Shinko 170 is an 80's profile tire VS. stock 150x15 is a 90's profile (and other 170 series tires). Do you think the Shinko will fit easier than others? i.e. no center stand rub?

No idea, never used Shinko's


EDIT:
I should've mentioned that about 95% of my riding is done on the freeways. So that probably has some to do with the good range that I am getting from my tires. Freeways tend to be in better condition than side roads so less wear I am sure. It works for me anyways.
