Hi Edwin Does this setup help to close the throttle more positively when you take your foot off the peddle. And does it make the peddle a little harder to press down, this would help on long trips so your foot can rest on the peddle without it accelerating. My throttle shuts quickly and has a nice feel for short blasts but it could do to be a little stiffer for the longer trips.
Cheers
Kevin

Not sure yet.
The second version feels better. Better pedal pressure and the second spring is helping closing the trottle.
Also the ratio between pedal and pulling the trottle is faster.
Avoiding steep bends also makes difference.
Of course above is personal.

I will be interested to see how you like the modification when you try it.

This evening first tests. Trottle response is very very direct, engine revs up and down very quickly. Tension on pulling trottle cable is much less. The pivot bracket also prevents 180 degree bend of the trottle cable. Next few day road test. I am looking forward.  |

Got new front springs for my tR1ke.
Original springs are way to weak. Only 31 Nm.
New progressive Hyperpro springs are 45 to 75 Nm.
Hyperpro spring type 370 is 100% perfect, less common therefore less available and only available in purple color.
Know it is personal, but purple springs do not match my car.
Hyperpro spring type 1365 is 99,9% perfect, very common used, therefore easy available also black colored.

Trottle is perfect. Faster response, up to 3rd gear wheelspin if i want to.

Hi Edwin
Its good to see that your throttle linkage has worked as you like it, it must have been bad before for you to create your own system. You will have to be a little lighter on the throttle now or you will soon need a new rear tyre.
I am interested in how the new front springs feel when you try them, Unfortunately they will have to be a different rating for mine because they widened the front wishbones last year. Mine are already harder than yours but not progressive.

Trottle response is very direct and more agressive. High yohohoho factor.
Front suspension was too weak. With driver + passenger the nose cone is scraping the road surface now and then.
With new springs it feels like front of the tr1ke is glued together to one solid massive construction. Speed bumps are no match.
Not sure about car hight, looks like the tR1ke is leaning 1,5 cm backwards again. We will see.

They are much stronger than original arn't they, the original springs must be very weak. I was thinking the new springs would be softer initially to absorb the small bumps and get progressively stronger for the bigger bumps and cornering. Are the Hyperpro springs off the shelf or do they make them to your needs. I would like some but Im lighter so your springs wouldn't work for me. If its too high at the front are you using the same static ride height as with the old springs, you could experiment with it lower as it shouldn't sag as much. Happy testing  |

The driver is a healthy average Dutch person: 1,85 meters & 90 kg (including clothing and helmet....)
The car suspension is original set for just the driver, no passenger.
(Driver side spring preload was set almost to max, passenger side preloaded to 1/4. Damping both sides to half way)
Hard steering into a corner results the car is diving (or rolling).
Adding a passenger to the car makes the car unbalanced again.
Worst of all: the nose cone is scraping the road surface very easily.
Happy testing indeed.
Will share my results.

Hi Edwin
Iv'e just seen the above pic with the progressive spring fitted, it looks like you have the preload set at minimum. Is it a longer spring and is the ride height any higher without your weight than before with the old spring.

Hi Kevin,
Your observations are correct. I lowered the spring preload as low as possible, but suspension is still a few cm to high. The tR1ke is leaning backwards, just by 1,5 cm. Higher speeds combined with some road bump results in a less stable situation and higher driver alertness is needed. Before the tR1ke was slightly leaning forward and sucked itself to the road.
The spring stiffness however is perfect. Front end of the tR1ke feels rock solid.
Last weekend I was out. Will make some more measurements and make a new visit to Hyperpro.
Will share my findings.

Last saturday finally had some time to visit Hyperpro for bringing my shocks and shared my findings and measurements.
Today got a mail form Hyperpro, shocks with new springs are ready. (black ones, of course)
New spring type will be: #1448/190/10.
These springs are a bit lower and less progressive.
Extra costs for this extra service from Hyperpro: none (€ 0,-)
As always: will share my findings!

Hi Edwin
It seems like Hyperpro are a good company with good after sales backup.
Hopefully you can test it before the winter sets in.
Cheers
Kevin
