I've got a 2008 KTM 690e with the H4 60/65W bulb which was oem that year. Even though it blows the later models' puny 35W? incandecent POS away, more light is always a nice thing. Baha Designs makes an HID upgrade kit that fits the 2009+ headlight bezel, but not mine so I'm trying to figure out what it takes to change my headlight/mask set up to the later models. Since I haven't actually seen a later model 690e personally I'm hoping you can tell me whether the later model mask bolts right up and the turn signals, etc work with it and whether additional KTM hardware is needed to make it work. I did order a 50/100W H4 bulb to see if that is an adequate enough upgrade, but running the 100W high beam with my electric liners and accessories is an overload so I'd have to upgrade the stator I think. I added a voltmeter to the bike to keep the charging situation in check. Thanks!
