The beam Rotax Max EVO (version 2021) is a masterpiece of origin manufacturer (Original Rotax Racing). This is the optimized and reliable version by the Austrian plant to correct the weaknesses of the first beams of the EVO range.
This electric beam centralizes all the connections of your motorization: it connects the battery, the start / stop button, the ignition coil, the electrical starter, and the electronic unit (ECU). Its reinforced wiring and car type connectors offer excellent resistance to the incessant vibrations of the chassis, with the moisture of races in the rain and projections of fat or gas.
Motor compatibility (range Rotax 125 Max EVO):
This beam is universal and settles on all categories of engines Rotax Equipped with EVO electronic ignition system:
-
Rotax 125 Micro Max Evo
-
Rotax 125 Mini Max Evo
-
Rotax 125 Junior Max Evo
-
Rotax 125 Max Senior Evo
- The trick in Michel (the corner of the expert)
* "Hi Ace the Electric Starter! If there is a sneaky failure that can spoil you a final or stick to the stand on Sunday morning, it's the fake electrical contact. The 2021 version of the beam Rotax was a well-reviewed sacrament at the pods, but karting remains a hell for electric wires because of the vibrations.
My trick of old pecker for editing: takele the path of your cables and use dielectric grease !
When you attach the beam along the tubes of your chassis or battery holder, never tighten your Rislan necklaces (cable clamps) as a wild. If the beam is too tense or compressed against the tube, the vibrations will shear the copper strands inside the sheath without being able to stand outside. Always let a little soft little.
When cliping the plugs on the coil or the ECU case, put a micro-dung silicone grease (dielectric) at the bottom of the sealed connectors. It prevents moisture from installing, it avoids the green oxidation of copper plugs and it guarantees a perfect conductivity even if you wash your water jet kart after a muddy sleeve. A clean and well guided beam, it's a "start" button that responds to the quarter turn every time! "*
-. The Installation & Connection Guide: Step by Step
1.Deposit of the old beam:10 min.Put the kart on its track trolley. As a safety measure, unplug the negative (-) terminal from the battery first. Then disconnect all the plugs of the old beam (ECU, coil, starter, switch) and cut the old fixing clamps.
2.Place and path:10 min.Present the new electric beam Rotax EVO 2021 on the chassis. Position the relay / fuse box near the battery holder. Make the cables properly towards the motor by avoiding the hot areas (exhaust pot) and the moving parts (steering column, back shaft).
3.Connexion and sealing:5 min.Follow the trick in Michel: Apply a key of dielectric grease, then firmly fit each keyless connector into its respective element (coil, ECU, starter). You must hear a "click" on the switchover guaranteeing the sealing.
4.Fixation final and Test:5 min.Attach the beam to the chassis with flexible plastic necklaces without tighting them. Connect the battery lugs (positive + terminal first, then negative terminal -). Put the tact and press the boot button to check the starter reactivity.
-FAQ SEO (Frequently Asked Questions)
Q: Is this beam 2021 compatible with old engines Rotax Max non-EVO (before 2015) ?
A: Not. The old generations of engines Rotax Max use a totally different ignition system (analog ignition with a combined red / black coil and a separate balancing box). This beam is exclusively designed for modern electronic architecture in the range Rotax Max EVO (equipped with the removable ECU case and the separate ignition coil).
Q: Are the relay, the fuses and the start button included with the beam ?
A: This product includes the full main wiring harness with its sealing plugs. Electric devices such as the contactor handset (ON / OFF / START button), the ECU case, the battery and the starter relay are items sold separately if you do not already have the engine kit.
Q: Is this beam authorized for FFSA official races and the Rotax MAX CHALLENGE ?
A: Yes, absolutely. This is an official piece certified by Brp-Rotax. It has the regulatory technical marking and is totally approved for all national and international competitions applying the technical regulation Rotax.
