Wouldn't they have less traction? compared to the more comonly used tyre's.

would these rims 'require' camber adjustment or will they be fine @ 90 deg ?

I have a set of disc tyres and yes they certainly do have a lot less traction. They slip sideways very easily

even with camber and slight tread on the tyres. They require very hard packed sand (for beaches) or they start to bog

@ Marty don't know whether these would require camber for the lateral force on the bearings

but would require camber for previous comment.

This sort of setup is purely for serious speed attempts :yes3: even though Nigel with his 98.? and Jason's high speed record weren't on disc's (correct me if I'm wrong) for general buggy the other setups are ideal. Big Foot Duro tyres on 4" rims on higher pessure work well for high speed, and work in soft sand too :good:

Unless you have a large enough area I'm not really convinced by discs, the lack of sideways traction will probably slow you down more than any other benefits you will gain from them.

Cambering isn't just about the bearings, it improves the loading on the spokes from sideways force.

It's more the foot pegs that are turning me on... Would it be possible to attach S1 foot pegs to an S2 fork?

Sorry failed to mention the S1 fork as a whole will fit the S2

Dont think there would be an issue with rake angle as that is done on the swan neck not the fork, would just be the fit between top and bottom plate over said swan neck mate :D

I was going to let this one slide through with out comment but since BGKD is asking about fitting them to the Vmax again I thought I'd make a quick mention of the difference between 'rake', 'offset' and 'trail'.

'rake' (as it is called on a motorbike) refers to the angle at which the axis of rotation is inclined. On a motorbike or buggy with straight forks this is exactly the angle of the front forks themselves. 'Offset' on a motorbike (or confusingly what is referred to as 'rake' on a push bike) is the distance the front axle is ahead of the axis of rotation. On a motorbike this is achieved with the triple clamps (the forks are always ahead of the pivot), on a push bike this is (traditionally) achieved by having the forks curve forwards. On the S1 the offset is achieved by having the front axle mounted in plates that extend forward of the forks. 'Trail' is the distance the wheels contact point with the ground is behind the axis of rotation. Trail causes the 'castor' effect where a car/bike/buggy tends to "steer it's self straight" when no input is given. The longer the 'trail' the stronger this 'castor' effect. The reason we have 'offset' is to reduce 'trail' and hence reduce the caster effect. The upshot of all this is that the more 'rake' you have and the bigger the front wheel is the more 'offset' one needs to keep the steering light. That's why when you see those custom Harley's with the exaggerated rake they have those tiny front wheels. As the rake becomes even more ridiculous you'll see these Harley's often end up mounting the front wheel on 'extender plates' (much like the S1 forks have) to reduce the trail even further.

The reason I mention all this is that although the rake is indeed defined by your buggies down tube/swan neck the offset is defined by the forks themselves. Assuming they can be fitted I should imagine the S1's forks would wind up being fine on a V-Max I'm just pointing out that if the rake is significantly different there could be a problem as those S1 forks do have a pretty mean 'offset'.

Clear as mud?

S2 fork = $296AUD

S1 fork = $455AUD

are these the standard bigfoot forks or do they do midi fork, what's the price of liver stainless bf forks

........and then there is this :)

Eye halve a spelling chequer

It came with my pea sea

It plainly marques four my revue

Miss steaks eye kin knot sea.

Eye strike a key and type a word

And weight four it two say

Weather eye am wrong oar write

It shows me strait a weigh.

As soon as a mist ache is maid

It nose bee fore two long

And eye can put the error rite

Its rare lea ever wrong.

Eye have run this poem threw it

I am shore your pleased two no

Its letter perfect awl the weigh

My chequer tolled me sew.

I discussed with him last season a redesign of the pads so the seams face down. I know they have implemented that but not sure about the Logo etc.

New seat is improved material and offers higher adjustment for those that want it.

Forgot to mention the logos on my buggy aren't upside down.

One side has logo at front and the other side has logo at the back.

Nice one Watson

Hmm, just poring over specifications.

I note the S1 is rated to 130kg while both the mild and stainless S2 are only rated to 110kg.

How strict is this rating? Anyone know what it is about the S1 that gives it the higher rating?

Given I have a nice manly 120kg frame (prone to topping out at 130) should I be committed to the S1?
