[E4] Front Rear sprocket change 17/45 (428 chain) RPS Hawk DLX top speed

Stock sprockets are 16 tooth front and 50 tooth rear with a 428 chain, I changed to a 17 front and 45 rear. Looks like about a 6 mph gain at same RPMs (comparing old videos) first gear is still plenty low enough for the trails too. 69 mph top speed I got on this run.
