"Magic Box" opinions?
« on: July 19, 2018, 05:46:18 PM »
Just about done with my restoration on the '87 K75c, now i'm on to the part I've dreaded the most: replacing the gauge cluster. Part of what retired the bike in the first place was because the glass and tach/speedo got completely smashed while it was in storage. Looking at OEM clusters fills my wallet with fear, so I'm considering aftermarket gauges and the Marulabs Magic Box seems to take out all the guess work with trying to configure a new one. I'm not the picky type, so I figure the box and a cheap speedo would get the job done for less than the cost of an entire "bratbox". Opinions from anyone who's gotten one? or are there cheaper options that plug-in readily/have cheap adapters available?

Looks a lot better than the stock cockpit. I imagine that its just a simple plug and play with the box?

Pretty much,

The rev counter needs an smoothing circuit, see this thread which tells you exactly how to do it. But everything else was plug and play. The cheap Chinese Speedo had a short lead so there was a lot of rewiring to do. I put my BEP under the tank but some people take them back to the electrical box. I added a lot of warning lights to give the full functions of the OEM clocks.


The speedo works great and I'm really pleased with it 20?. Those Chinese seven year olds put it together well  :hehehe, Time will tell how reliable it is but so far so good.  :2thumbup:
