Front Brakes and Rotax

[Mathieu Seguin]

Hi guys!

I am shopping for a chassis to compete in the Rotax Max Sr class. I have noticed that the new chassis almost all have all front brakes.

What is the benefit of having front brakes in the rotax class ?

Should I spend more and get a 2009 chassis with front brakes ?

Thanks

The Rotax DD2 karts use front brakes but I don't believe Rotax Senior are allowed to use them.

Front brakes are optional for Rotax Senior. The following is clipped from the RMC Technical Regulations (http://www.maxchallenge.ca/html/documents/2009_RMC_Technical_Regulations_Canada.pdf):

"Junior MAX and 125 MAX classes
Round tubing only.
Maximum diameter of rear axle = 50 mm, minimum wall thickness according to CIK-FIA rules.
At IRMCE and RMCGF chassis with a valid CIK-FIA homologation only are allowed.
Any brake system must have a valid CIK-FIA homologation.
Front brakes are not allowed in the 125 Mini-Max and 125 Junior MAX classes.
Front brakes are allowed in 125 MAX class only.
For Canada, all braking systems must be operated simultaneously by a single foot pedal unless
necessitated by physical handicap and approved by the event scrutineer.

125 MAX DD2 class
For all national RMC, IRMCE and the RMCGF 125 MAX DD2 classes, chassis approved by BRPROTAX

www.maxchallenge-rotax.com).
Chassis must be designed according to CIK-FIA rules for shifter classes (front- and rear brakes

Any brake system must have a valid CIK-FIA homologation.
ROTAX Rear Tire Protection System is mandatory to be used. Either old 2 tube version or latest 3
