Twin pack of long M8 speed bleeders for brake calipers with 8mm bleeder nipples. Simply loosen the bleed nipple and an internal check valve allows fluid to flow out, but nothing can flow back in.
This size fits Brembo 4 piston calipers used on most Guzzis since 1998 and many late model rear calipers as well, including the 2004 and later V7 series.
To verify measure your bleeder nipple to find 8mm across the threads. Standard size M8 x 1.25 thread pitch.
