Ive found relatively little info on the interwebs about this specific flavor of blue KTM. So, now a place to consolidate info, ask questions, point out the differences in this and the citrus version. For starters, on the FE501, the 'berg has that the citrus does not: -New WP 4CS 4 chambered fork -Machined triple clamps -Plastic Skid Plate included -Plastic Subframe -Different airbox configuration that is part of plastic subframe -Larger Tank capacity due to lack of emissions gear -Blue DID Dirt Star Wheels -Lack of kick starter -Different seat -Perty blue plastics... Anything else. Experiences to relate? I'd rather this doesn't become a thread to lament the change from the 70 Deg motor...it was great but....onward.
