the height franke sloothaak jumped to achieve the world puissance record in 1991
Puissance The puissance wall often has become taller than 2 metres (6 ft 7 in). The current indoor record for puissance is held by German rider Franke Sloothaak, who in June 1991 jumped 2.40 m (7 ft 10 in) in Chaudfontaine, Belgium on Optiebeurs Golo, breaking his previous record set on Leonardo.[1]
Freestyle motocross In 1991, Jose Yanez became the first person to backflip a motocross bike. He practiced for it by flipping his motorcycle into the Salt River, just as he had done with his BMX bike. He would kill the engine on his 80cc motorcycle just before he hit the water to prevent damage to the bike. Yanez performed the world's first ramp-to-ramp motocross backflip on an 80cc motorcycle in October, 1991 on an 8' tall box jump he built himself in Pagosa Springs, Colorado. Jose's next motocross backflip attempt, this time for The National Enquirer resulted in a crash that kept Jose off motorcycles and bicycles for two years due to an injured knee.
