Something Darksiders Don't Want To Acknowledge

[Bubba in TX]

I was just thumbing through the STAR Touring site I belong to and another Yamaha site at the car tire threads. (as I have several Yamahas) It's funny, but in those threads about car tires it's all about what size and or brand do I need, how long have you ran them, I have a (insert motorcycle model here) and want to try one. Not a single "you will all go to hell if you use a car tire" person....

You want to see people talk about car tires go into a Goldwing forum.... I see more of them on Wings than any other scoot.

Only reason you don't hear from those with an issue with the car tires is simple: They're dead!

Car tires on bikes are a bad idea, period. They are engineered for four wheels and a completely different driving geometry and suspension behavior. The contact patch is severely compromised on turns. For those who use them all I can say is: do you know what "denial" means? It means "don't even know I am lying (to myself)". And you dark siders are in some serious denial. So it doesn't matter how much the facts hit you in the forehead, just like all the smokers out there, you aren't quittin'.

That is typical talk from you guys that have your head up your ....fill in .. never tried it have you? If not ......well you know.

I believe only the ABS bikes have linked brakes. When you apply the rear brake you get some braking on one rotor up front. When you apply the front brake you do get some rear braking as well.

I like it because I don't have to move my right foot if I don't want to, but if I need to slow down quickly both brakes need to be applied.

I'm not sure if you are referring to ALL bikes or just the VV, but I know that linked brakes are on all Honda VTX 1800 models, but ABS is not an option. I believe all Honda GL1800's have linked brakes, and ABS is included in one of their "packages".

I haven't done an in depth search, but all I can find from Ma Kaw is something like "...balances input to ideal pressure for front and back...".
I guess it doesn't really matter. If I have to make an emergency stop; I'm not putting my trust in linked brakes anyway.

I use my rear brake alone for slow speed maneuvers.
Other than that I have gotten into the habit of just putting my foot on the pedal when shaving off speed.
More of a 'muscle memory training' than anything else.

I think that's wise. It's one of those things that's Just a Good Habit. Flying over the handlebars hurts.

To a degree.

There must be a functional relationship between the aftermarket part and the warranted item.
Bob's example of a damaged fender meets the requirements; a cracked head does not.

If you put non oem speakers in and your radio gets damaged they COULD use that to deny a warranty claim.
If you use a non oem luggage rack and your sissy bar gets damaged they COULD use that to deny a claim.
If you use non oem pulleys and your gearbox gets damaged they COULD use that to deny a claim.
But, you never see the warranty nay-sayers warning of doom and gloom on those threads.

I always like looking at the pics of the bikes in the BOTM threads. They are beautiful machines!
I don't think I have ever seen warranty concerns expressed over how modified those machines are.

I wonder why that is?

Scott

Where did I say anything materially different than this?

Moreso to the point, a broken radio is hardly worth gloom and doom consideration. Tires, on the other hand...

At 900lbs; I don't think I could get my bike to do a "heelie".
And the ABS should keep the front wheel from locking up causing a low side.

Theoretically; if the brakes were ABS and linked @ 70-30, that would be the perfect ratio and you could just mash the pedal or grab the lever as hard as you can for the best possible stop.

However; technology can fail, and I may find myself riding a bike without ABS or linked brakes someday.
In that situation; I want muscle memory to put my foot on the pedal.

That may be an an incorrect interpretation of my post. My intent was about investigation whether or not part "X" contributed to a failure, therefore whether or not the failure would be covered by warranty.

For example, we have empirical evidence that shows if you don't use a hydraulic filter of certain specifications, or better, the hydraulic system will not remain below the cleanliness levels necessary to prevent premature wear.

We private label an off the shelf filter that meets or exceeds this spec, and that same filter is available private labeled under different brands as well. So, you don't have to use "our" filter. However, it's an expensive filter no matter who you buy it from. Then there are other filters people have found that "will fit" the filter assembly and are much cheaper, but don't keep the system adequately clean. This can be a very expensive lesson in frugality.
