Dr Big - Dr750 Preload adjustment fork caps

Pages: 1 2

Is there a bolt on?
What's the thread (34 x 1?)
Is the 90 to 95 Dr650 the same fork cap? Different part nos...

I`m not aware of anything that will fit the DR750 forks in the way of preload adjustment.
The 650 forks have a different thread as I`ve been down that road.
Maybe a fork cap off the GSXR 750/110088-92 will do the job as they were 41mm and had a 3 way preload adjuster, though no idea if the thread will be the same.
The Big is so agricultural that it doesn`t really need this, well, to my mind anyway.
Have fun with your search Wink

Used the vernier, reckon irs 1 but yeah gotta get one!

The company in China who make these asked if I could draw up ours to see if they can produce it cost effectively so out with various cans of beans and sauce bottles for circles as my kids have lost my lovely old brass compass.

I'd imagine if I approached an engineering form here a set of those would run in the hundreds.

I find the front end of the Big more than firm enough so I really wouldn`t want any more preload.
Mind you, I do have progressive springs which help, but even standard springs wouldn`t benefit either imho.
Methinks someone is a compulsive twiddler Wink

btw admirable draughtsmans display there Big Grin

I guess I like playing with suspension Bob As I'm fond of saying, better than pi$$Ing it away down the pub but yes possibly my ocd at play!

My tuppence is the most basic thing you can do suspension wise is getting the sag right. Pretty much every bike these days has it. Everybody sets the rear shocks preload and the fronts works harder again when you consider braking.
With the 29l capacity is being able to hand tighten a few turns of preload my ocd or a meaningful change? I don't know but considering the efforts I've put in I'm willing to try it for 30 quid. Should have them in a month or so. Will bore yiz all with the pics ha!
Now I'll l deffo be able to keep up with Dave#22 with Pat on the back on his bone stock suspended dr
