and the Top 1 Ack Attack crew battled through adversity all weekend long to set a new motorcycle world land speed record of 376.156 mph at the Cook Motorsports Top Speed Shootout 2010. After a first run where Rocky said the Ack Attack streamliner wanted to “heel over to the right” followed by gearing issues that almost prevented them from making a final run, Rocky and the Ack Attack crew pulled it all together to make a record-breaking run down the Bonneville Salt Flats. The Ack Attack streamliner’s exit speed was an incredible 394 mph while its kilo record was 376.363.
Here’s how the moderator from the Landracing Forum for the Top Speed Shootout 2010 recounted the historic event in his post from the scene:
“Bike is moving - heading towards us -- we're now at the four mile.
Entry 379 Mile 386
HE DID IT!!!!!!!
What a run, what a rush to see him blow past us.
Official speeds entry 379. mkilo 387.1 milke 386.9 exit 394 mph. WHOLLY SH*T.”
Robinson once again holds the title of world’s fastest man on two wheels after recapturing the title he lost to Denis Manning’s BUB 7 streamliner. His 394 mph exit speed is the closest yet to the magical 400 mph barrier teams like Ack Attack and BUB 7 strive to shatter. Here’s what Robinson’s team posted on his official site.
“What a year it’s been. To summarize, Rocky has taken the record back on September 25, 2010 at 376.363 mph after losing the record he held from the TOP 1 OIL World LSR Shoot Out in 2008 to his rival Chris Carr on the BUB Streamliner at the Cook's Shootout in 2009."
Robinson barely managed to break the 300 mph barrier on his first run after experiencing difficulties with the streamliner’s aerodynamics tilting to the right. Later, Mike Akatiff and team had to deal with an engine that wouldn’t shift into fifth or sixth gear.
Check out this post written by the moderator in the Landracing Forum chronicling the problems that plagued the team right up to the last second.
“So if the bike wouldn't shift beyond fourth (well, one engine would, the other wouldn't) -- well, what to do? While Rocky was in the pit he was brainstorming. Mike Akatiff went to the lawnmower pit (about 5 miles down course) to join in the celebration and while he was gone Rocky got the idea of re-gearing so fourth would maybe do it. He called Mike, he and Mike talked to the gear guy and decided that such-and-such sprockets would be right for 385 or so in fourth, and they decided that what the heck, there wasn't much to lose if it didn't work -- and everything to gain. So they dug around in the parts boxes -- witness this stack of rear sprockets.”
The adversity Rocky and his team had to overcome makes their accomplishment all the more remarkable. Congratulations, Rocky and the Ack Attack team on your world record-setting run. Can’t wait for you to share the story in your monthly Motorcycle USA column, Salt Addiction.
