RFX Pro Series F8 Taper Bars are designed and tested at the highest level.
F8 Taper Bars are manufactured from 7075-T6 aluminium and feature Oversize Taper Extension (OTE) to give the ultimate strength and crash resistance, whilst Engineered Flex Technology (EFT) and Progressive Damping Control (PDC) helps provide just the right amount of flex and reduces machine vibration to help combat rider fatigue.
F8 Taper Bar design also features an original type cross brace, this gives a slightly firmer feel to the handle bars over the F7 design and is the preferred choice of some expert and professional racers.
OTE is a lengthening of the central oversize (28.6mm) section. Increasing the oversize section to run past the final bend in the handlebar adds significant strength to the weakest part of any handlebar, couple this with a 5mm wall thickness that stays consistent even on the outside of the bends and the F8 Taper Bar is one of the lightest yet strongest bars on the market.
EFT is designed to give a small amount of flex in the bars. Carefully selecting an inner wall thickness of 5mm through the rise and taper area of the bars helps to reduce the effects of jarring in large impacts whilst providing the rider maximum front-end feel in corners. The F8 bars have a slightly firmer feel than the F7 thanks to the incorporated cross brace.
PDC is created using a larger wall thickness of 5.3mm on the handlebar grip area, this has been calculated to balance and dampen against the effects of handlebar vibration. This is a similar principal to the handlebar weights used in sports bikes but is specifically designed and tested to suit the vibration range produced by modern high performance 4 stroke motocross bikes.

QUESTIONS & ANSWERS
Have a Question?
Be the first to ask a question about this.
The most important helmet fitting aspect to consider before determining helmet size is helmet shape. The shape of the rider's head plays a crucial role in selecting a proper fitting motorcycle helmet. All helmet manufacturers design their lids to fit a specific head shape. These often range across three primary designations - long oval, intermediate oval, and round oval.
- Long Oval - Shaped for a head which is longer front-to-back (from forehead to the back of the skull) than it is side-to-side (ear to ear).
- Intermediate Oval - Shaped for a head which is slightly longer front-to-back than it is side-to-side. Most motorcycle helmets will fall into this category as it is the most common head shape; if a helmet does not state its shape, this is usually it.
- Round Oval - Shaped for a head which has almost identical front-to-back and side-to-side measurements.
Once the head shape is determined, it is easier to filter the enormous selection of available motorcycle helmets down to a smaller, more appropriate list of those which will fit the rider's head. Now it is time to find the correct size of the motorcycle helmet.
Helmet Safety Standards
DOT Helmet Standard: This stands for “Department of Transportation,” (not “doin’ our thang”) but the standard is FMVSS 218, the Federal Motor Vehicle Safety Standard #218, Motorcycle Helmets, and it is applicable to helmets sold in the U.S. for on-road use.
ECE 22.05 Helmet Standard: ECE stands for “Economic Commission for Europe,” which was created under a United Nations agreement in 1958. The 22.05 part refers to the specific regulation that the standards for testing are described in.
Snell (Snell Memorial Foundation M2010) Helmet Standard: The Snell Memorial Foundation is a private, non-profit organization formed in 1957 dedicated to improving helmet safety. Snell goes beyond the governmental standard-setting approach and is available to assist manufacturers with helmet development by offering prototype testing.
What is MIPS technology? MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. MIPS has been developed by leading brain surgeons and scientists to reduce the rotational forces on the brain caused by angled impacts to the head.
