Yamaha RD250/350/400/R5/DS6/DS7 Parts:Ignition:MZB / Zeeltronic Systems & Components

Replaces the stock magneto, points, condenser, coils and regulator found on the RD, R5 and DS6/7.
This system includes a lightweight external magnetic drum rotor and stator, ignition controller and HT coil pack, regulator, plug wires and caps, misc hardware and installation instructions.
This is the same type of ignition you would find on any modern motorcycle and gives you a high voltage spark and strong electrical output for lighting and charging. This is a maintenance free system, you will never need to check your timing or replace / adjust any parts as you would with contact points and condensers.
In addition to the written installation instructions and wiring diagrams included with the system, technical support is available from Economy Cycle and MZB via phone, email, and website support.
24 Month Manufacturer’s Warranty.
35,000 Volt HT Ignition Coils
Electrical output at 150W/12V allows you to run high wattage lights, halogen bulbs, and any accessories you like. Your horn, signals and headlight will be strong and bright even at idle.
No changes, modifications or machining needed to install this system
This system does not require a keyway / woodruff key and you can run the static timing of your choice. (typically RD’s and similar bikes run in the range of 1.8-2.4 BTDC).
The system is capable of running without a battery.
Very stable ignition with high energy spark for better starting and fuel efficiency
Increases engine performance and lowers emissions
Wasted spark system ensures easy starting
This system is manufactured to exacting standards and all components and machining are top notch and the highest quality. Just what you would expect from a German company.
Manufactured by MZ-B Powerdynamo, imported from Germany by Economy Cycle – an authorized US distributor.
You will need a basic understanding of motorcycle electrical systems and basic mechanical knowledge to install the system, or you can have your own mechanic or local bike shop perform the installation. Economy Cycle can also install this system on your bike or motor.
The system typically takes 3-4 hours to install.
Note: requires puller tool - available here on the website under the Yamaha RD350/400 ignitions category.
No additional relay required for this kit to use your stock ignition switch.
Some notes on keyway cutting and woodruff keys: Keeways and woodruff keys are not intended to keep the rotor drum from slipping and absorbing a shear load. They are designed to index timing, and once a keeway is cut and woodruff key installed, your timing is permanently fixed and cannot be changed, we don't recommend this modification for these reasons.

You can combine this MZB system with a fully programmable Ignition Controller from Zeeltronic to enable a dynamic timing curve and rev limiter. These components are offered here on the website, exclusively by Economy Cycle.

Zeeltronic VCDI04 CDI & Programmer for use with MZB Ignition on RD's,R5,DS6/7

Programmable Ignition Controller and Handheld Programmer by Zeeltronic for Yamaha RD250/350/400,R5 and DS6/7.

Do you want a dynamic ignition curve for your RD,R5,DS6/7 allowing you to dial in the advance you want across the rev range? Do you want complete fully programmable digital control over your bike's ignition curve? Would you like to instantly monitor revs and timing angle in real time? In the palm of your hand? How about a 3 stage rev limiter and optional handlebar mounted map switch that allows you to change ignition curves on the fly? This system has it all!
This is a bundled package and includes the Zeeltronic VCDI04 Ignition Controller, Zeeltronic Handheld Programmer, instructions, resistors and wiring diagrams (items can also be purchase separately).
This system is an add on to the MZB ignition, giving you the ability to have dynamic timing and other features on your RD,R5,DS6/7 and early water cooled TZ250’s. This system only works with the MZB digital ignition and other bikes with CDI’s, it does not work with stock magneto/points/condenser type ignitions. To use this system you must first upgrade your stock RD,R5, DS6/7 stock ignition to the MZB CDI ignition, also available here on the site.
Fully programmable dynamic ignition curve, dial in the advance you want across the rev range.
Real time monitoring of revs and timing angle while the bike is running
Real time programming while the bike is running - you can immediately see effects.
Store up ten custom programmed curves on board.
3 stage rev limiter, stage 1 retards timing, stage 2 reduces spark, stage 3 cuts spark off completely avoiding over rev and blown motors.
Easy and fast programming via handheld programmer. Programmer connects via cable to VCDI04 and allows you to program curves and see real time read out of revs and timing in the palm of your hand.
Programmable from 200-20,000 RPM’s. Dial in the advance you want in as little as 100rpm increments.
Circuit is protected against reverse supply voltage (wrong connection).
Signal delay compensation – allows you to accurately set your static baseline timing.
High speed processing for optimum accuracy.
Zeeltronic - Truly the worlds only fully programmable dynamic ignition for the RD,R5 and DS6/7.
Available only from Economy Cycle.
