People and Federations complain about high cost of the SGP3 class but till they race on this kind of tracks, too fast and too big for a 250 cc. engine, the problem will never stop!...Try to race in a 1000 mt. track on a 500 cc speedway bike and you Will see...

SGP3 qualification round 1 in Pardubice:

Andzejs Smulkevics place the fastest heat time powered on ®️evolver and score 3 win, 1 second in 4 heats. Unfortunately in 1 heat a clutch problem produce a zero (T) before the Start.
As you all know Pardubice Is a fast and big track... probably too big for 250cc! ...but thanks to the rider, to the good work of the team and the equipment the Speed was incredible.
