    The Service Honda digital ignition represents a huge leap forward for the CR500 engine. This ignition completely transforms the bike. The transformation is appearent as soon as you start the bike, turn the choke off and let the bike idle while you put your gear on… the bike will not stall, rather it idles streadily, that is just the beginning of the improvements.

    Once your gear is on and you are riding the bike the next thing you notice is the improved throttle response and big increase in low end power. The improved low end power make the bike even more of a joy to ride, this bike just does not stall. The low rpm power makes for smoother overall power delivery and faster lap times on a moto track. The smoother power enhances traction, something that is always an issue with the power of the CR500 engine.

    Off road riding is improved even more with the digital ignition. Throttle response on long technical down hills remains consistent through out the decent with the new system, a quick twist of the throttle produces instant power to easily clear an obstacle. The engine flexability in the most technical sections is almost magical, no stalling no overheating. When the trail opens up the power is urgent and immediate jsut like you would expect.

    The digital system uses 26 points of change in the map with a new point every 300 rpm compared to the old analog system that used only a few. The vast increase in the number of maps results in much smoother power delivery. The smooth power really improves traction vastly, even on a hard slick surface resulting in faster times and less rider fatigue. The power is so much smoother you can be fooled into thinking the new system makes less power, this is not the case the digital system actually makes a bit more power than the old analog system.

    The Digital Ignition also comes with a high power light coil that puts out 130 watts with a flat output curve that means even at idle there is plenty of power for powering lights and accessories. And the whole system fits inside the stock ignition cover so it does not interfere with your ability to shift the bike, an important detail for anyone who wears a size 8 boot or larger.

    The digital ignition is must have for anyone riding a CR500 of any kind.

      What Customers Say

      “I have to say that the digital ignition was a vast improvement over the
      stock setup. It transforms the stock (jump up and bite you) power delivery
      into a very tractable and predictable power band that really makes exiting
      out of corners or hitting that quick jump effortless! The beauty of it all
      is that you really don’t have to down shift the bike very much……it just
      pulls seamlessly and without any protest. Starting the bike is routine and
      predictable and in my opinion, it is a must have for any CR500!” Tom.

      Campbell River B.C. Canada here. I talked to you in May about the digital ignition system. Just got one from you and installed it. The bike hooks so much better at first I thought it had way more power. After 30mins of riding I realized its just getting to the ground. Huge increase in 3rd and 4th gear unintentional wheelies. You know the ones where your arms are straight because your falling off the back of the bike,and your thinking wholly shit.

      No more warm up stalling,no more loading up in trails. The double kick thing is going to take few days to prefect, but its coming. Very happy with Service Honda and your products. Byron.
