Stu­art Hicken

The boss of Hawk Rac­ing. He has been in­volved with build­ing race en­gines since the 1980s and has built both the team’s pre­vi­ous BMW S1000RR and cur­rent GSX-R1000 race en­gines, which both use fin­ger fol­low­ers. “Con­trary to pop­u­lar be­lief, fin­ger fol­low­ers are not some­thing new to bikes. How­ever, they of­fer a po­ten­tial gain in max­i­mum power over the more con­ven­tional bucket and shim de­sign. Used to ac­ti­vate the bike’s valves, the sys­tem uses off­set camshafts, with small fin­ger fol­low­ers each work­ing on their own valve.”
