Having owned three different Sumos now, I thought I'd update the info on this thread.
2006 Volkl Sumo (brown leather topsheet)
Published dimensions: 175cm = 145-125-142
Actual dimensions: 178.4cm (tape measure straight from tip to tail)=149.1-124.8-142.5 (wider than published), 64mm high tip (12mm higher than the 2008), 23mm high tail (lower and shorter twin than the 2008)
Weight: 2,280g
Notes: Found this on an old thread: "While the sumo is not rockered, the tips are huge and have a long rise on them. Two different generations of sumos exist. the brown (first) ones measure about a 180-182, but have a smaller contact area from the freaking huge tips. The new generation measures a true 175 and the tips are more subdued. The twin on the tail is relatively small."
2007 Volkl Sumo (black leather topsheet)
Published dimensions: 190cm=150-125-142 and 175cm=150-125-142
Notes: Volkl added the 190cm length and shortened the 175cm.
2008 Volkl Sumo (black with Sumo wrestler graphic)
Published dimensions: 190cm=150-125-142 and 175cm=150-125-142
Actual dimensions: 190cm=187.3 tip-to-tip, 52mm high tip, 29mm high tail and 175cm=172.5 tip-to-tip
Weights: 190=2,440g and 175=2,170g
Notes: 190cm length measures about 14.2mm thick at waist, 175cm length measures about 13mm thick at waist, typical glossy topsheet, lighter wood core (tips & tails CNC honeycombed) than earlier versions, clear sidewalls.
Factory boot center mark on 2008 190cm is about 1.25cm forward of traditional alpine mount and about 1.7cm behind the center of the sidecut. Boot center mark on 175 is 5cm forward of traditional alpine mount (possibly placed forward for female skiers) and is at center of sidecut.
(For reference my 183 Bro Fats measure exactly 181cm using the above tip-to-tail method.)
