I have seen some on this forum say they have installed the XCS hurricane on their 250, and I tried looking for any impartial reviews but I have not been able to easily find a review, good or bad from any reputable motorcycle site. Most of what I found were blog sites that read more like sales brochures, many with the same exact info and grammatically incorrect wording looking like it went through a machine translator. This makes me think that it may not do anything useful.

As I understand it the XCS is a capacitor bank that will normalize the available current on the bikes electrical system. The stator will output bursts due to the way it is made. Batteries have a lower instantanous current availability than capacitors and this helps to level out the peaks and valleys. If your ignition fires during a valley you see a cooler spark, and this will help rectify that problem.

Sounds good, seems to work on paper, but I wanted to know from anyone with actual experience whether they work or not.

While batteries are fast capacitors are WAY faster for higher current discharges. From an electrical engineering standpoint the theory makes sense I just dont know if it pans out in reality. Or at least that is what they taught me in college.

What makes it seem shady to me is the fact that there are no real reviews by any of the larger magazines or really anything but blog sites that are nothing more than ad copy and not even reviews and the ad copy is all virtually word for word the same.

I also forgot to include the url to the site for the specific question (most of the material is in Indonesian (I may have said Thai originally, that would be incorrect). hurricane indonesia

I actually learned about this product from this forum so I figured it would be a good place to ask. It has been listed as a mod installed so I started googling originally to just find out what it was which naturally led to my curiosity of "does it work".

Here is some additional information. It appears that the theory that I thought was correct is not, it is not a capacitor bank just a voltage regulator. There is a lot of background information on why this is a problem, at least with some bikes. They also give schematics so you can build one for about $10 or so.

I still want to hear from someone who has actually installed one on their bike and what they observed in terms of performance. The dyno results that XCS publishes as part of their sales material says 2HP and 4Nm more torque, but it does not appear that it is that much of an improvement percentage wise. Being Indonesia I have no idea if they tested on a smaller or larger bike, 2HP on a CBR250 is about 8% but on a Hayabusa it is about 1% (or less on some models). It is also difficult to translate the image through a machine translator and I do not know Indonesian.

All my bikes using XCS , start from NSR R 96, NSR SP 2001, Ninja 250R 2010, CBR 250R.

As we know that stable voltage for electronic devices is a must to avoid shorter life of the component, this XCS just stabilize the voltage glitch come the coil. So the voltage get into the CDI or ECU will be much better and it makes the electronic component will last longer and in other way, stable voltage will makes the CDI / ECU works more accurate and the result will makes the combustion better.

I haven't to measure it with Dyno Mechine but i feel the bike response is much better.

Voltage Regulator.

This is a voltage regulator for an automotive style Alternator. It is used with an Alternator that has a Voltage Controlled Field Winding Coil.

The cbr uses a Permerant Magnet Rotor for the Alternator.

This unit won't work on the cbr.
