Bolt-on Cognito Moto BMW Airhead Subframe kit. We have recreated the loop shape using compound radii so the loop comes to more of a point at the rear. One of the biggest challenges when creating a seat is reducing the size towards the back. Since this loop gets smaller, coming to a point instead of larger, creating an aesthetically pleasing seat is a lot easier. To create loop a specialty freeform tube bender is used. Specially made slugs CNC'd to match frame angles perfectly. Shock mounting is designed for stock shocks or OE replacement. We have also included is CNC Laser cut and formed seat pan that matches the loop and bend as well as a matching base pan. This will save you a ton of time and headache trying to match the sheetmetal to loop shape. Ready for foam and upholstery. Offered with or without integrated LED strip or KOSO Hawkeye taillight. CNC a holder and pocket in the loop for the super bright Koso LED tail light. or Inlayed LED version no longer available images need to be updated. Truly a one of kind piece. It's the little details like this that really make your bike stand out.
