Hey Neil any progress?
Not much as yet,I've been chasing folk about my driveshafts and my bodywork recently so not much machining has been done. This coming week should see the front end in properly,extensions and all,and hopefully some risers made up as well.

Cool. Good to hear about that... im plastic fabbing as well. Need to get that rear end done before my bling gets here for assembly... Have a good week... Cheers
Extensions done,fitting up this weekend hopefully......
Started on a couple of billet inserts,these will be anodised black then engraved with my logo design.....
And I've decided to remake the hub to use a larger disc,and also make it lighter through some redesigning.

Looking good, those extensions look oversized compared to what I've seen. I can't wait to see what's next, you just can't beat the look of machined aluminum!!!
The final product should be sweet looking that's for sure!:thumbs up: :thumbs up:

I already posted this on customfighters Neil But here it goes again...
"Dude you don't stop... I wish i could do the same... Do you have a lathe with a big enough chuck to hold that alu log?... lol
Didn't you make those sleeves/extensions way too sturdy? How thick are they? 1/2" looks like it... I think you do not need them that big, especially when having such a deep lower yoke... Remember that you are adding up weight in the front of a 300Kg bike that is using a <200Kg bike stock front USD forks... When you'll need to brake the USD will collapse in a jiffy... Start thinking of racetech 1,2Kg coils and maybe thicker oil... Take a look below
http://old.racetech.com/evalving/menu/searchstreet.asp
Just choose your USD model from the list and it will calculate the proper spring rate accounting on riders and bikes weight... In your case you'll be needing the stiffer ones that i believe to be 1,2kg... "

The whole bikes oversized dude! :rofl_200:
The forks will be shrouded with 3" tube come the finish. So yeah,kinda chunky!
unk:And replied over there......we'll see how she rides,I'm expecting this to be a process of refinement over the next couple of years! Cheers for the link....

Cant agrre about that.
Firstble my v-max was around 230kg, Im not sure from where did you grab 300kg's? Stock is about 275...
I hope to drop some more this winter.
Its not about that those 1kg springs are to soft for a v-max.
They will propably be ok for most v-maxes.
Why?
Cuz the v-max neck angle ratio...yes angle creates a ratio.
You need to read some more anout this couse its not that easy.
Hes extensions are to beefy for sure LOL

Prez keep up with me
You are correct that the Vmax has a bigger rake (AKA castor angle, angle between vertical and forks at the steering neck) than a R1 or other sportbike for instance (where the USD came from) and its because of that that you need to have stiffer suspension. When you are braking the force is in order to bring the front wheel closer to the rad (no brainer) and if so, the more vertical the USD are the less they are compressed (trigonometry 101), and at an extreme if they were to be horizontal they'd be compressed to max extent possible on braking (ie the full braking force would be applied on compressing the forks and nothing applied on levering force at the triples).
The stock Vmax is 280Kg dry so thats y i pointed to a roughly 300Kg fully serviced with fuel and oil... Plus the riders weight...
When i crashed i "stepped" on the brakes and the stock suspension went to the lower detent, now imagine how it would work out for a stock sport USD... This is common sense talking and i nver tested this but as i see it thats the way its working, but if im wrong i'd like you to correct me... But with facts... :Wink2:
PS - What you say regarding rake is for static suspension wise only (force divided in compression and momentum around the triples pushing wheel forward)... But when it gets to the real deal... riding performance its like i said... At least for all i read so far thats the insight i have...

Yes, Archimedes firstable then a center of gravity/mass diffrences beteween v-max and sport bikes - cosmic diffrence.
Then the axles widht, swingarm angle and other very important things.
You can freely call by liar anybody, who claims that any suspension swap is simple like driving a supermarket chart...
276 to be exactly, kg more for cali versions.
Diving is not dependable from spring rate as much its dependable from commpresion damping. V-max comp. damp. is an acient history - or should I say v-max dont knows what comp. damp. is at all.
Cartridge forks are diffrent style of ride - im still learning about suspension tricks and rules but, its complicated as much as engine kinematics.
I dont recomend 1,2kg springs for non stock v-maxes. Too stiff, way too stiff
in my case (i will mention that im 100kg weight man).
1kg is a good choice for me.
Need to whole more work with damping and rebound.
Rebound is a ***** to properly set up!
And good hint from Jim/vmaxrider as i also have found very useful.
Preload of forks is very critical.

I didn't intend to call liar to anyone. Just pointed to the fact that most likely it will be needing work on suspension due to the major differences they have now on the Vmax... And the numbers i gave came from racetech themselves but one thing is true as well. I entered the weights but they assume the bikes arquitecture is maintained (R1 in my case) and not Vmax (where the forks will feature). So those 1,2 kgs may be false, i acknowledge that... And i never said that is simple to start brainstorming about suspensions... Im just a common mortal that likes this stuff... Im sure there are people here that know all about this due to the fact this is a common mod on Vmaxes... Let them express themselves so we can learn a bit more... I think that is the gist of this forum... Having more brains thinking for the benefit of all... right?... Either way thanks for the input Prez

It was a free allusion LOL - its all good.
Why so serious?
I never said that you said anything.
Am I too honest?

im no native speaker as well but if you check the quote on my last post you'll see y i understood you were "accusing" me of calling liar to somebody... lol If im mistaken disregard all this and lets go to the sandbox... ;o)

Yup, not native as well haha
Well,for what it's worth,I'm just going by what feels right. If you saw the original incarnation of the bike it was using ZX9R RWU forks which felt absolutely fine,didn't bottom out two-up,even in stock trim! I'm not expecting the bike to ride like a racer,and I sure as hell don't ride my bikes that way-if I did I wouldn't be building something with such massive tyres! Hence why I'm saying I'll give it a try before I go panicking about revalves and springs.
Road bikes have to be a compromise by their nature,able to cope with a 10st rider as well as 30 odd st of rider and pillion plus luggage. Plus a guy I know has run a custom 'Max on stock R1's with heavier oil for aout three years now with no complaints,so I figured its worth a shot.
RE machining marks,too fast and worn tip mate,but the outer face will be polished and anodised and the inner will never be seen once fitted so it's all good.......:biglaugh: You two have got me thinking about slimming the extensions a little (possibly)......

You all are so far over my head, I'm awaiting more pictures. I would think this is going to one of the most radical bikes ever... No matter how the math works out... It'll be a personal expression. I build some of my rifles and people say "That'll Never Work" and when I'm done, they fight over who may be able to buy it... Press on Pingu, you have my blessing....:biglaugh:
