R1 forks on Vmax

Any one know how to go about fitting R1 forks to Vmax.
I know the Vmax forks are longer than the R1 so how do you go about extending them
Would you need to upgrade the fork springs to cope with the extra weight. Cool

Would I need to use R1 yokes and will these fit onto the max ok.

wdnt it be easier just to sell the vmax and get an r1 ?

You might need to get new yokes specially made to make them fit.

That's what I have to do anyway but I'm fitting yamaha parts to a suzuki bike.

It's probably worth finding some R1 forks and trying them out first though.

You'll screw up the frame geometry. I suspect that by adding shorter forks to a bike which has a reputation for 'interesting' handling, you'll probably create a slap happy bike.

I'd invest in a very good quality steering damper.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Mar jay & Finglonga, If you look in street fighter mags you can see many examples of R1 forks fitted to the vmax & it looks quite cool, Shocked

If you read my post you would notice it said (I know the Vmax forks are longer than the R1 so how do you go about extending them). this should & will cure any problems with frame geometry, Middle Finger

As for the handling its quite obvious you have never ridden a Vmax, although they are not up to par with todays modern crotch rockets the handling really is not that bad. Shocked

Still need to know how to go about extending R1 forks.

still seems daft to me
it may look quite cool but i think vmax forks are better on vmaxs and r1 forks are better on r1s

the forks are designed for that particular bike and are set up accordingly

but im one of those idiots who gets a bike for the way it rides rather than to get attention at bike meets.

when will i ever learn eh

You've got a couple of choices, both will cost you money though Sad

.
Fork extensions where you can replace the fork tops with a longer piece to bring them to the right length but then you've still got to have yokes made/adapted to fit them to your bike. It's not the strongest to do it that way especially considering the extra weight of the Vmax over the R1
Have a set of stepped yokes made where the standard R1 forks fit but the tops are a bit below the top yoke making them the right length for your bike. You're looking at around £300 or more to have them made though, places like TES do them.
Your basic steering geometry remains the same as does ground clearance etc. if you use stepped yokes you might gain an inch or so of wheelbase.

Third choice that Bezzer forgot is longer Stanchions, the knuckles are removable.

he said he has a vmax for its looks

Sorry to but in randomly but isn't adding extra inches to stanchions a bit dodge? I'd much rather have some custom made if I had the cash. Welding extra inches just doesn't seem safe to me. But that's just my Penny Coin

_edit_
Again I don't know the set up on a Vmax but can't you use emulators and stiffer springs to solve handling problems?

I am drunk so maybe doesn't help.

Dear colinWall I dont ever remember saying I got a Vmax purely for its looks, I wish to make a few mods to my bike that will will enhance its performance, and at the same time improve its looks in my opinion.
Apart from the looks there are other benefits, along with R1 front forks comes the whole front end, R1 front disc's and the whole braking system, this in its self would be an improvement to the stoping power,
Sickpup & Bezzer many thanks for your help I think I might look at stepped yokes Thumbs Up
