SYM VTS 200 CDI

Capacitive Discharge Ignition Units (CDI), these device store charge and let go at a "bang" , modern bikes and cars uses these to get better combustion and cleaner exhaust. It need more that CDI to do these anyway.

Above SYM VTS 200 CDI, apart from having those Capacitive circuits it also have rev limiting built in, these to safe guard the engine from abuse and operates at a safer range to prolong engine life. This Standard CDI is about RM 140.00 a piece at the spare shop.

There are after market replacement which sell for less, something like RM 50.00 on ebay. These work just as good.

Or for the more adventurous and need the rev limiter removed, they could opt for the racing version averaging in price from RM 75.00 on ebay like below.

Point to note before ordering these, make sure its suitable for your bike and the connector is the same.


Below typical circuit diagram for a scooter, exact for the VTS 200 is similar however the colour coding of wire may be different.

The racing CDI selling at Maju Motor or even Sentul is about RM 250.00 each. I don't think it worth that much, considering its "Plug & Play" and its not really that great in performance improvement on a scooter. As they said.. you wanna go fast.. get a Superbike.. a scooter is for leisure and relax commuting.

BTW you might as well change the ignition coil to racing spec, while you are at it.

This standard coil price about RM 50.00 each.
