The ADR3
Overview: Overview: The ADR3 was designed around the Honda K20 2L automotive powerplant and mated to a Hewland FTR 6 speed sequential gearbox. The chassis is also capable of accepting the Suzuki Hayabusa motorcycle engine mated to a driveshaft and Quaife differential. This gives the ADR3 customer the ability to participate in everything from casual track days to the most grueling enduros. By keeping the Honda motor relatively stock, with the exceptions of the dry sump, ecu, and headers, customers should expect 2 – 3 seasons of enduro racing before needing a rebuild. Track day customers should exceed these figures.
