Posts: 49 Lillian, Alabama | I've got a 08 Vision with 8k miles on it (it has to share ride time with another bike so don't give me a hard time about the low milage ).....for the past few weeks, when taking a turn at slow speeds it feels like the back tire is about to slip out from under me. Any idea's on what might cause such a feeling?
I'm running about 46 psi in both tires....71 psi in the shock. Everything feels tight except when doing the slow speed (15 - 25 mph) turns. I don't notice it as very slow speeds or higher speeds.
One other things, a couple of years ago, I lost it in a curve because I hit some gravel and the back slid out on me, so I know what that feels like....3k damage to the bike and road rash and a couple of broken bones in my hand.
Is this all in my head? or is there a mechanical problem behind it? |

| I think you are way out of "whack" on your tire and shock pressures...Way too high for comfortable riding/handling.....Most here run 39/41 front and 40/41 rear on tires and 20/25 psi in rear shock . Check your owners manual for tire and shock pressures and you will find that your tires and shock are way over the reccommended pressures......Good Luck... |

| You're a might high on the tires and way over on the shock. I run 40 in the rear and 38 in the front. 31 in the shock.

The tire pressure seems a bit high, but not sure that 46psi would cause the rear tire to slip out under normal conditions. Are there tar snakes in your area? The combination of high shock and tire pressure will exaggerate tar snakes. ??? |

| Get your rear wheel off the ground and see if you have side to side movement. |

That's going to drastically reduce the footprint. As stated earlier, get the rear off the ground and make sure the rear axle and swing arm haven't any side play. Then lower the tire pressure to 41, shock to something on the order of 25, and give it a go to see what happens. Also, there are some hard riders that have used up an E3 tire in 8k, so give that a look. Running 46 you may be well through the rubber in the center line.

1. Set front tire psi to 40 (38 - 41).
2. Set rire tire psi to 41 (40 - 42).
3. Set your shock to around 25 - 35 psi. 71 psi is when you are loaded, the bike, not you.
These are cold psi, not after a hard ride.
Do put a jack under the bike and check out any play, though I doubt you have the problem, but you must rule it out based off of symptoms. Also, sand and other stuff on the road will make you lose it, so don't rule that out either. Let us know what you find.
Ride hard, ride long, ride safe! |
