From February 2018 Christini will be offering a All Wheel Drive kit for the KTM 1290 Adventure.
The complete DIY Kit is priced at $3500USD and no frame modifications are necessary to fit the All Wheel Drive kit to your 1290 Adventure.
So far the only picture Christini have released of the kit is this very blurry picture of a KTM 1290 Adventure where you can just make out the All Wheel Drive kits hydraulic lines running down the front of the fork legs.
