Recommended modifications for KTM Duke 200 / 390
Now the Duke’s have a decent headlight but for the speeds it can do, it probably could really use some lights with a stronger and further throw. One of the easiest mod that can be done is replace the stock bulb with one that has a better output. Now when we say better output we do not mean higher wattage. The stock electricals will not be able to light up a higher wattage bulb effectively and the extra heat could also melt your reflectors. We recommend the Osram Nightbreakers or the Philips Xtreme Vision bulbs in the 55/60 W rating. We do not recommend HID’s and LED’s as they work better with projectors, on the normal reflectors they just scatter the light everywhere without proper focus.
Other options would be to mount a secondary lighting unit on the handlebars or crash guards. There are several options for LED and even projectors with HID setups that are a simple bolt on and easy fit. Do your research properly before going for these, especially in terms of the power rating of these external lights. They should be of 12V and correct wattage / lumens and ideally connected to the ignition with a separate fuse and switch. Also use them only when needed as you risk draining your battery due to the extra load on them.
We want our motorcycles to do everything and that means we tour on our naked bikes as well. Now the Duke being a naked bike does not have the the best wind deflection and as the speeds increase there is more stress on the rider especially while touring. The easiest replacement is to get the windscreen from the Yamaha Fazer, it’s a direct fit. The second option is to fit the CBR250R windscreen. It is more sturdier than the Fazer one but you are going to have to drill holes at the right mounting point. Easy enough to do if you have the right tools.
3. Seat upgrade
This one is for the real mile munching riders. From a street use perceptive the Duke has good seats. But when it is your touring machine of choice you need some extra cushioning to feel your assets after a long ride. Easy fixes are getting a gel pad and getting a ready made softer seat with better cushioning built in. For those who have a little bit more time on their hands, extra cushioning can be easily added to the existing seat, just take it to any of the many seat cover makers.
4. ECU upgrade
Although not a necessity there are advantages to having this done. For one, you get a wider power band with better low end performance, making it a more comfortable ride. Another advantage is that you get a better efficiency than the stock setup, while this largely depends on the way you ride, it is true that it works. Suggested ECU upgrades on the Duke 200 and 390 that you can look at are the ones the guys at Powertronics & Kiirus have to offer.
