PKT's original OTK gauge mount adapts a MyChron 4/5/5S or Alfano 6/7 to an OTK 4-spoke steering wheel (Tony Kart, Kosmic, Exprit, Alonso). Machined from .075" stainless steel for support and corrosion resistance, it fits both straight and angled steering hubs and mounts behind the wheel with full access to the battery and rear ports. Sold individually.
