Foward a-arms = weight transfer?

[rb0804]

Are the foward A-arms help with weight transfer? I already have a +6 swingarm and am going to be in the market for a round house in the future. Would it be better to add the 2" to the swingarm or hang the extra 2" out of the front with the A-arms? Racing on asphalt. Thanks

They are supposed to help with weight transfer. I got a set of -1 +3.5 from Tim at Stellar but havent got to try them out yet since my bike isnt finished. They sure look puuurdy though. Give him a call and he can tell you all about them.

It really depends how much power you have, wheelie bar or not, and rider weight. That's just to name a few items to consider. From a safety stand point I would rather see +14-15 degrees of caster built in for straight line stability.

The plus forward arms do help with weight transfer. But for asphault I would still recommend a wheelie bar. Depending on your weight, you dont want to go with too long of a swingarm to help keep some weight over the tires.

 

And just like Slowerthanyou stated. For Asphault you really want somewhere between 12-15 degrees of negative castor. I have built a few sets of the -1+3.5 forward drag arms with the negetive caster built into them for the asphault guys.

I don't want to disagree, but my references is positive caster is for straight line stability.

Actually positive castor will help you to turn easier, negative castor will help keep your wheels going straight. If you had 14-15 degrees of positive castor, it would be a death trap going 80-100 mph down the strip.

I can give more references.

I would send you a PM, but I'm unable.

I guess it has been explained incorrectly to me all these years. I was always told if the axis of the pivot point, pointed forward, it was a positive castor. And if it pointed rearward, it was negative. But it makes perfect sense that if you look at it clock wise, you would want it moving forward, or in a positive direction.

 

Good info right there. I stand corrected!

I've been very luck in my 30 year racing career to learn from a lot of people. I'm not new to the game and I know you didn't mean it that way. We have made around 700 1/4 mile runs on our quad over 4 years time. Most of our Motorsports experience we used on the science project.
