Birel R axle


(Christopher Ramnauth) #1

Does anyone on here have any experience with the new Birel Art R axle on a RY30 tag chassis? Does it provide more or less rear grip?

Here is the Birel axle chart about 2/3 down this page - Birel set up info.

Here are my notes from Birel tuner Cash Van Belle from Tkart.it (https://www.tkart.it/en/magazine/expert-advices/right-axle-right-moment-cash-van-belle/#2)

Track Conditions

  1. Lot of rubber – choose a rigid axle, because it frees the chassis; decreases the grip [just the outside edge of the inside tire on the track] and helps to more effectively unload engine power when coming out of a bend.

  2. Slippery Track – a more flexible axle is needed; allowing the rubber to work in your favour, since it gives more grip on the asphalt

Axle Type - Soft v. Hard

1. Hard - MORE GRIP AT THE REAR

2. SOFT AXLE -- LESS GRIP

Long (1040) v. Short (1000) Axles

1. Long - track has mainly wide bends

2. Short - short axle is preferred if there are narrower bends

Right Axle Mounted?

**Jumps under braking - rear is too rigid; the axle does not absorb the stresses of the chassis & transmits them to the tyres; mount a softer axle
