I’ve featured a few “CR500 engine into CRF450 frame” swapped bikes before but the amount of additional upgrades on this bike is absolutely staggering.
The seller lists out $26,489 in parts/costs, ignoring the labor. Beyond the engine, it has an Aprilia RXV swingarm, Alpina supermoto wheels, Lectron 40mm carb, Pro Circuit header, custom exhaust with carbon fiber Scalvini cans, Renthal bars, Beringer front brake kit, and Ohlins suspension…the list goes on and on.
