Been running the combo for over 5k miles so far. Great combination as far as I'm concerned, the TKC front and K60 rear seem to wear at about hte same rate too which is nice. Great traction in the dirt. I'm not willing to test the edges on the road (not on any tire for that matter) but for as hard as I've pushed them they've been perfect.

Can you post a pic of your rear K60 and state exact mileage? If you can... Thanks my man!!

Im running a 140. Not sure if its related but Im about 3 miles behind for every 100 on the ODO compared to the GPS calculated mileage.
I also never balance my wheels and cannot tell the difference even at 90mph.

That's a 3% speedo error. I'm distracted and low on caffeine, but I THINK that means your speedo reads high... Easy enough to verify since you have a GPS. Just crank her up to 60 or so (higher speeds are better) and compare the GPS to the on board speedo.

The stock speedo on my 800 is pretty accurate up to 45 or so and not off by that much at higher speeds (like 5mph at 80, which is more than 3% error).

The 140 is actually a taller tire than the 150 due to the different aspect ratio. This will make the speedo and odo read low when using a 140 compared to the 150.

Well it is definitly off. 3 miles every 100. And now 8.8 miles low when approaching the 300 mile mark comapred the 276c readout. Looks like it will click -9 at 300.
Do you fellas think the tire could be the reason ?

Yes, it most likely is the prime cause. Also, remember that no matter what tire you run, it will change as it wears. Therefore, it will become smaller in diameter as it wears.

A 140/80 measures out to a height of 112mm. A 150/70 measures out to 105mm. This, of course, is having all things equal in terms of radius, profile, etc.within the tire design.

Don't forget your GPS isn't dead nuts accurate. It can lose signal from time to time along with other issues.

All in all, it's close enough so don't over analyze it. Just ride it.

Do you want that from straight on??





(Sorry, had to make a Sundance reference . . . )


I'll try to remember to do it when I get home.

[DockingPilot]

Oh, no I dont really care one way or the other. Except Im anal about 2k mile oil changes and, well the thought of me going over...............

Never noticed it until last week rideing home from the ADV Rider Eastern Rendezvous and I rode 550 miles in 1 day. I was bored.

Oh no you don't!! I ain't taken no oil thread bait about what to use and how often to change it!!! Uh, no way.

[DockingPilot]

Dam, foiled again.

Ok Griz, here you go. I put it on when the bike had 5,499 miles, it now has 10,262 so that's 4,763 miles. I didn't measure the tread depth when new (wish I had). Now it measures ~ 6mm. It's hard to measure and the angle wasn't right. It looks like it's 4mm deep but it's 6mm. I also did the quarter for perspective.

Hope this helps:

That's cool ! I betcha the tire tread new must have had a depth of around 10mm. At least that what TKCs are when new.

My first K60 rear (140/80-17) was right about ~12mm when it was new. I didn't measure the 2nd one to see if it was any different.

My rear K60 also measured 12mm (actually 11.5mm) when new.

Too bad I damaged the bead when installing it and now I'm stuck with only a K60 front and the stock rear.

What an idiot I am.

God bless,
