Preload 2016 Speed Triple R

Triumph say that on all the 955 Daytonas and Speed Triples too. Daft.

 

I adjusted mine, think the warning is just arse covering by Triumph

 

Dave Moss gives a brilliant class on setting suspension

 

Pre load is how compressed the spring is

Compression is how firm the suspension compresses when hitting a bump

Rebound is how fast it returns to its unsprung position

 

I have softened the spring pre load bump and rebound on my 16 as at 12 n half stone i found it to hard, i also dropped the legs through the yokes.

 

I am 16st (all muscle ) and in full leathers the suspension at the front is too soft - I have a zip tie on the front and it bottoms out each ride on the road with preload almost at maximum

The front springs are 9 N/mm and using an online calculator for my weight and bike weight I should have 10 N/mm fitted

Weight with gear value = me plus leathers, helmet etc
Bike weight is dry weight plus an estimate for oil, coolant, and fuel etc.- plus any baggage

1 kg/mm = 10 N/mm

 

Red Thunder, you could add length to the spacers inside your fork tubes, I'd start by adding approximately 1/4 of the spring travel, would that be about 4 inches or 100 mm ? So about an inch or more , I added 35 mm to my standard springs on my initial setup adjustment on my America, but it didn't cure the damping issues. So I bought emulation system with 11 N/mm springs for my 95kg weight, plenty stiff enough now and I have lowered the front about 20/25 mm , sharper steering gained as well ! I tow a trailer which fully loaded weighs as much as 200 kg. So I need a good stiff front end for good control whilst braking ! I also put tapered roller head stem bearings in for same reason !!
Hope that is of some help.

Cheers capt.

 

I'm running the "comfort" damper settings, but I've also reduced tyre pressures to 32psi front / 36psi rear. Advice from other threads on here suggest "standard" tyre pressures are too high.

 

Having shed about a stone in weight recently I’ve put the damping back to factory settings after I’d increased all round by plus one turn and have just come back from 120 miles around Derbyshire’s finest twisties and I think it’s better than before.
How do you find the bike with 36psi in the back tyre Col, i run with 38 in the back and 32 in the front?
That’s on Roadtec 01’s.

 

Checked my pressure today's and it was way up compared to a few weeks ago
Front was 42 now 34 and return was 50 now 42. Maybe the hot weather had greatly increased it.
Also increased preload in the front by one turn to reduce sag to 40mm, as it was still bottoming out each day (cable tie method)
I may have to increase compression too but that would really form up the ride, I really need heavier springs in

 

Hi Red Thunder,

I use the zip tie indicator as well. I had to soften my fork to get closer to the bottom. Now I have about 15mm of safety buffer that I never seemed to hit so far.
For the fun, I build up a small suspension preload calculator for the speed triple see attached file.
It isn't refined to the point to take your own weight in consideration, but if you have a buddy to help you with the tape measure, you can dial things in;

That sir, is a fantastic suspension calculator.
I will have to try this out with my bike...I am sure I need to increase my springs from the standard 9n/mm to 10n/mm

 

You're welcome!

 

Speed Triple R springs are 0.5 N/mm stiffer than on the standard Speed triple.
