I used the first production PP/PR system on my Sport (Laguna) Coppa build and I have never had any Derbi idle soooo very smooth and steady. I would suggest using a small gel-cell 12V battery and a switch with it for lights-with-the-engine-off. Upgrade to a hi-lo headlight and rewire the brake lights with late Tomos brake light switches. Hot blue spark, not pale yellow. I suggest using a 6 mm dowel for the screw hole @ the timing mark for dead-on timing-sighting. a lot of bucks but so very worth it. Update: I also installed one on my RD-50 along with the usual changes going to a 12V system. I did find 2 of the factory 335 Rinder headlight housings so now I have low and high beam on my Laguna and RD! Looks like a factory install on both of them!

mounted up & timed super easy to a C5 & RD. coil & rectifier fit perfect under the tank, wiring is super clean. Both held up in the Pinball Run 2; 1400 miles in 7 days. 300+mile constant running days in 90*+ heat, not a single issue. great spark (running NGK BR#IX).
major benefit was the lighting circuit. 12v DC can use car bulbs, super cheap/available everywhere. wired in a supercap battery and everything was stable at idle while powering 35&10w lights, ~40w UEGO sensor, and 5w USB/Phone charger.
downside: no ignition curve on the stock box was a surprise at this price, but easy to fix. out of the box ignition-wise it's like running super strong points. also had a paper like rubbing noise when hand turning the crank after installing them, never could find the culprit- both work fine regardless.
if you're debating on this vs the HPI mini: go for this on your daily cruiser, bright lights/super reliable. go HPI for performance on a sport setup.
Great System!
