Before he got with mobibuff, he saved every penny from work to race. He's literally put his life on hold for his love of the sport, he's actually even now still not making a living racing. Lucky for him Greg (mobibuff) pays for all his flights, back and forth from bc to Vegas, pays for his hotel while he's racing.
The trailer, the bikes, the gear, the canopys, all fees including entrance, tires, food, gas ect are payed for buy Greg.
Greg and marcel met through his YouTube vids, Greg called him up and wanted to sponsor him, and now marcel has made a big name for himself in the USA racing.
When I was with the team in Cali racing the superbike shootout, the costs of pro racing became really clear. You simply can't do it without being rich, or getting a big sponsor.
