Dricked, how was you experience with adjustable clamps with Gen4, did handling improve for you?
And are you planning to use stem inserts to change rake with Gen5?

Gen4 race: high spec.
Suzuki GSX1300R Hayabusa 2013: stock.
Kawasaki KX450F 2016: love it.

When are you next going to Brands? Im thinking of booking the GP day with No Limits 3rd May for 179

Need to get the bike dialed in first.
That sounds very tempting. I can never tell this early but i will probably be going to this. What bike you riding?

Take your shock off and have it serviced and setup for your application or it's just a blingy waste of money.
If only i had the time id like to do a race but maybe when i grow up lol.
I got offered a ride on a classic honda this year but its not really my cup of tea.
Think i will just stick with track days as occasionally you find someone pushing on hard and you can have a good battle with them. And it just seems less time and agro than racing.
Maybe one day i will get everything set up properly but its just not priority right now in my life. Trying to renovate a house whilst doing 60hours a week at work with 2 kids at home just doesnt leave much bike time (unfortunately)

Would be nice if someone would explain basics of subject "preload" as parameter affecting suspention dynamic properties.
Relationships with topout spring or what brings reducing one mm preload and compensating it with one mm of shock length.
What happens as you start accelerating out of corner, rear starts to squat at certain shock shaft speed. When shaft speed ("getting shock going") is low or high, then besides compression damping the preload plays role here too?

I didn't ride the bike with the stock clamps so I can't give a fair review. I don't plan on changing the rake on the new bike but I do have triples coming.

Tell me about it. I'm not renovating but trying to get/stay in shape for the upcoming season and getting everything sorted there's not much free time. Get your liscence and just show up on Saturday night to race Sunday morning. It's fun and no pressure!

Indeed, with Gen5 excessive trail can be pulled both ways.

This raises intresting question, hope Evallatra would enlighten us:
Lets say we have two bikes with EXACT SAME trail numbers, one has low offset (26mm) clamp, but smaller rake and second bike has bit more rake with more clamp offset.
Given that trail is same, are there some specific handling differences between these two bikes?
Just a question out of academic intrest.

Not that it matters anything for us, I remember when Rossi changed to Yamaha he specifically asked for very large offset clamps because he liked the feeling from them.

Basically, pre-load makes your suspension sit higher or lower in its range. It does NOT change spring rate. You can change dynamic geometry...the geometry of the bike with a rider on it without affecting basic geometry numbers such as measured by EV's magic machine.

Check out Step 5 here:

Suspension Setup Guide | Sport Rider

While it's technically true that pre-load affects more than that, for the most part dynamic geometry is what matters.

Thank you to my racing sponsors Riders Discount and Alpha1 Vinylworks

You forgot fat. Old, fat, and slow. :) Eric keeps threatening to fit my bike with truck springs but so far hasn't come through. ;)

Testing my 2011 ZX10R for the first time.

Shoot me a PM if you want more info.

May be going with a mate on an S1000RR

Also, I just realized that geometry sheet is not the one for my bike. He did mine last year.
