The Vit 701 suspension thread

Hola,
I need some help with what I think is a dumb question regarding Andreani's replacement cartridges for a Svartpilen.
I chatted with someone on the Rottweileer website who told me that the cartridges for both the Vit and Svartpilen were the same and that I would not lose any fork travel on my Svart by putting in said cartridge.
Is this correct? I do not have any in-depth technical knowledge of how the internals of these work, but I always assumed that the spring and cartridge length would determine the total travel of the fork.
Can someone please let me know if I'm wrong?

Sounds odd, there's like 7mm difference between the two...

So they are different, I'm not completely wrong about it.
For full disclosure, the Rep did say they would contact Andreani to make sure that what he told me was accurate.

This has always confused me too. I've also been told the svart uses the same nitron shock as the vit, which has never made much sense to me considering the 15mm difference in travel length......
 
On other vehicles, with more wheels, the suspension upgrades which I performed have always resulted in a change in travel, sometimes more and sometimes less.

Maybe thats the case here as well, the parts will "work" on the Svartpilen with the "side effect" being a change in travel?
 
Hi,

I'm new to this forum, but riding the Vitpilen for some time now.

Having no time to ride for a while I was thinking to convert my vit more towards fun Trackday riding without the constraints of tüv or whatsoever..

From my past experience with the vit on the track I've noticed that it's hiding it's obvious strengths pretty well. For a bike of this weight I felt it to be not very well turning, especially going into faster corners with less braking. At the exit of the corners I felt it ran away from me a bit, so I was struggling to stay one the line i planned to take..

So im thinking about pragmatic mods to achieve a very nimble machine, that's at least handling like my CBR600rr (pc40).. looking at the numbers it shouldn't be a big deal, right?

So what I took from reading through this is:
1. Change the fork oil to sae15 or 20 and also add additional oil to avoid hitting rock bottom under heavy braking
2. Lower the front by 10-20mm
3. Change the shock to a duke 690r one to make use of less stiffness and therefore more damping in the rear.. may be even getting a new one from hyperpro, nitron or so
4. Lifting the rear a bit to quicken steering (as by lowering the front) and increasing the ground clearance. Don't know how much is helping and when it's too much.
To my knowledge there are two solutions available to lift the rear with a standard shock.

Do you have further thoughts on this?

Kind regards

I had similar issues with mine. Almost impossible to stay on line in corners without decelerating, and running wide as soon as giving some gas. Plus had to turn the front adjusters almost all the way in to deal with massive break dive.

Nitron/Andreani/Hyperpro would cost me a fortune due to customs and exchange rates. Found a cheap 690R shock and let a local suspension tuner rebuild forks and shock. Hard to find compatible springs, so ended up with 6.5N in the forks instead of stock 6.0, and modifying the stock 110N spring to fit the 690R shock (I’m about 80 kg without gear). 3wt oil in the shock, and 485cc 5wt in forks. Together with a shims job, the bike feels much better. Sturdier under hard breaking, much easier to stay on line, and deals with track roughness without any drama. No change in ride height.

Have only had two track days since rebuild and haven’t ridden a proper sports bike on track, so can’t say how it compares to a 600rr. But way better than stock and can no longer blame the suspension for not being faster. Might still get away with complaining about the tires though ;)

Thanks for the input!

So the rear shocks of the 690r does differ not only in spring stiffness (less than those of the vitpilen), but also damping characteristics? ... otherwise it wouldn't make sense to fit the vitpilen spring into the 690r shock right?

Sounds like a set of minor changes that will help a lot with the issues I felt before.

Will look for a new set of handle bars which presumably will only fit beneath the upper triple clamp. Why? In my opinion the orientation of the stock ones are to straight/open.. i like them to be more like on a classic sportsbike because that will hopefully make me feel more engaged with the bike when hanging off.
A side effect could be that there will be more of my weight transferred to the front of the bike which alone will quicken up steering. I guess I could use a set of stiffer springs in the forks then.

My tire choice would be Dunlop Sportsmart TTs to start with. They last very long, offer good grip and do not need to be warmed up before every turn.. what do you use?

Kind regards
