I am…
Old Harbour Customs

Hi! My name is Thomas. All of this began with an abandoned motorcycle, brought back to life in a basement storage. Four years later, that spark has grown into a drive to channel my creativity into something tangible. I build K-bike custom motorcycles guided by intuition and craftsmanship — designs that evolve as I work, powered by technical expertise and relentless dedication.

My main focus is the customization of BMW K75 and K100 motorcycles using an ‘ethical’ approach. I only customize K’s that are not economical to remain ‘purist’ K-bikes. Via this website, I sell salvaged and aftermarket parts, service products and build a portfolio of my creations.
