Front forks anti dive

Post by 4given » Thu Jul 11, 2019 7:14 am



I need input on GL1500 front forks anti dive. I acquired a set of front forks online with the idea of rebuilding and having a spare set. When I received them, I notice there is only one anti dive unit. It’s on the right tube. The left side has none. Is this normal? The original forks on my ‘96 Aspencade has anti dive on both sides. Pics to follow.

Thanks in advance,
Dan

Those are from an earlier model. 1988.

My '92 Interstate is that way.
I asked about it in the "how-to" section on changing front tire (did not get a response), the tutorial shows one on both sides on WingAdmin's bike.

From what I am seeing in all the parts manuals from '88 through '98, the interstate models did not have anti dive valves on the left fork tube.

Steve,
Do you think I will notice a big difference with just one anti dive vs two?

Thanks for the info,
Dan

The feel will not change much but there is the issue of not having a place to fasten the left caliper correctly. I'm pretty sure the left anti-dive attaches to a caliper linkage like the right side. Never having an interstate I don't know how it attaches.

Interesting and valid point Mike. I will be checking that out the first chance I get 👍

Thanks again wingding. Just read through that post and I remember reading it before. And I’m sure I will be reading it again more than once.

The practical effect of having the single right side anti-dive (like my 93 IS) is that you will find yourself intuitively using the right handlebar brake which actuates the front right caliper only, more vigorously.
I replace the right front pads twice as often as the LF and rear.

You'll notice immediately that using the foot pedal (only) makes the front end dive. I USE that effect to "bounce" my front end such that the headlamps dip and rise, to make myself more apparent to cages that look like they may pull out in front of me. Especially effective at night and dark mornings (when I ride to work).


For the best panic stop performance, I hit the RF brake hard, THEN apply generous rear pedal. Doesn't dive doing it that way.
Even normal stops, I apply that front and follow to completion of each stop with the foot pedal. Works well for me.


When all else fails, RTFM!
