Abstract
The invention is a motorcycle with a main frame (1), the main frame (1) holding a rear swing arm assembly (2) with a rear wheel assembly (3), said main frame (1) holding an engine (12) and a drive train (13) connected to the rear wheel assembly (3). The main frame (1) is connected via a pivot joint (9) near the main frame's (9) upper, fore portion to a top frame (7), and the pivot joint (9) has a transverse axis (9′) relative to the main frame (1). The top frame (7) has a rearwards extending seat frame (8) provided with a seat (15) and a forward extending steering neck frame (5) holding a steering neck (6) further holding a triple tree assembly (14) with a front fork assembly (4) with a front wheel assembly (10). The main frame (1) is provided with an actuator assembly (16) for providing rotation of the top frame (7) relative to the main frame (1). The actuator assembly (16) is connected at a first lower end (161) to a lower connection point (17) near a rear portion of the main frame (1), and connected at an opposite, second upper end (162) to an upper connection point (18) at the top frame (7). Thus the motorcycle may be adjusted for rake, trail and seat elevation between a racing…
