Aftermarket wheels for new National SUPERBIKE rules

[Biggles08]

Superbike rules are out! Seems we can NOT use aftermarket wheels, no aftermarket triple clamps, no Traction Control unless its standard id say.

We can use diff pistons which is interesting

mmmmm....well this is interesting news. Not sure I understand the about face from MNZ on this matter...It doesn't mention wheels at all in the rules.

No matter what happens fella its all been good publicity for the rims.

You 'racers' that think stock suspension can become 'dangerous' when it gets hot are soft in the head. Bit like saying we should shorten races in case the tyre gets too hot and become dangerous!!!

It's a fact of life/racing. Ride accordingly.

I agree, I would rather race a bike in the dry with a standard shock than a kitted bike in the pissing rain. What is deemed "safer"?

AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA
MNZ never wanted the wheels it was the brain trust idea and celarly the distrbutors and MNZ said F Off

Id have to question if the allowance for rear links is because of the 09 R1 link( a model with a very progressive link ratio ) In which case you cannnot blame them for pushing that but many will question conflict of interest if a Yamaha team is resurrected.

Maybe, but there was a KCT "sponsored" superbike near the front last year with non standard links fitted, at least it would be legal now. And it is pretty obvious what you are trying to get at - but if the people you are obviously digging at have no interest in contesting the superbike class this season why would a rule that dosn't concern them be a conflict of interest?

can you explain to me how this is an about face, you heard a rumour about a rule that might be changed, and when the rules were annouced the rumour was wrong,

where is the about face???

seems to be you just got wrong information?

If you are talking bout my honda steve you are wrong AGAIN we changed the Dog bone thingy which was allowed never touched the link

This is straight off the CARROZZERIA website FYI:

Carrozzeria Forged Rims are 20–40% lighter than stock, depending on model. Reducing weight on a motorcycle will always make it accelerate, corner and brake better, but some weight reductions are much more valuable then others. Motorcycle weight can be classified in two ways; sprung or unsprung and rotating or non-rotating. Wheel weight is both rotating and unsprung, which as you will read is the most significant weight to remove.

Sprung weight is everything that suspension holds up, unsprung weight is the wheel, sprocket, caliper, disks, axle and a percentage of the shock and swing arm. Unsprung weight is the nemesis of the suspension in the war to maintain tire contact with the tarmac. The less unsprung weight the more effectively the suspension and ultimately the tires can do their jobs. To explain this lets pretend you had a job in which you had to raise and lower a hammer as moving obstacles came by on some sort of moving conveyor belt. First you had a hammer with a 1 pound head. As the conveyor belt moved faster at some point it would become impossible to move quickly enough and the hammer would be hit be an obstacle. If you used a hammer with a ½ pound head you would be able to negotiate the moving obstacles at a greater speed. Now imagine the hammerhead is the wheel, your wrist is the suspension system and the moving conveyor with obstacles is the bumpy tarmac. This is why most cars have independent suspensions. Reducing unsprung weight will improve the traction especially in bumpy corners.
Rotating weight on a motorcycle counts twice every time you accelerate or brake. The reason for this is the engine must increase both the wheels’ linear velocity as well as their rotational velocity. It is a little more complicated in reality, but each pound you remove from the wheels is equal to approximately 2 or more pounds removed from the chassis. Reducing the weight of you wheels will allow your bike to not only accelerate faster, but brake better as well.

An additional benefit to reducing rotating weight it the reduction in gyro effect of the wheels. The easiest way to understand this is to conduct an experiment at home. Get the front wheel off your bicycle. Hold the axle with your hands and have a partner spin the wheel at a moderate speed. As the wheel spins pretend you are the forks and “turn” the wheel. You now have a feel for gyroscopic forces. Now imagine what a motorcycle wheel with much greater weight and speed goes through when you attempt to change directions quickly in a in a series of turns.

Your seriously barking up the wrong tree mate....a set of wheels are not going to make you fast enough to run with the front guys....listening to them might!!!

Dont think you were aloud to change that either? Prop not aloud those hi comp pistons in my bike either but no drama.

Yamahas apparently need the link changed

There was a proposed set of rules out which allowed them but it was squashed about an hour ago

Soooo meny people sooo full of shit , I think you ment CKT ,nothing wrong with there bikes

Did you not get a copy of the proposed rules??? In those they were allowed...now in the final rules they are not mentioned....about face right there.

What the fuck is your point Cowpoos?

[onearmedbandit]

Now that is all settled, maybe they could offer some sharp deals to road riders.

But not me, I'm too broke.

I think a nail just got hit on the head
