"The bike got a lung full of water and slowed for a lap while it digested the fluid. Mitch Rowe (of New Plymouth) sensed I was having issues and closed in for the kill. But, with a lap to go, the WR450F cleared its throat and I was able to hold on for the win in the final river race.
"I chose to ride a Yamaha WR450F, rather than my usual YZ450F model bike today, just for a change. It was about as enduro as you can get with working lights, a side-stand and everything.
"The bike behaved really well in the wet conditions, but I guess that's what it's designed to deal with, crossing rivers, creeks and mud bogs in the forest."
Dubbed "The Axeman" , the former Manawatu forestry worker won two major cross-country titles in the US last season, clinching the Grand National Cross-country Championships (GNCC) and the Off-Road Motorcycle and ATV (OMA) crown as well.
Whibley will defend both crowns when the two competitions kick off for 2013 in a few weeks.
"I head back to my base in South Carolina this week, to get ready for the GNCC and OMA seasons.
"I get back into the race scene over there in mid-February, with the first round of the OMA series and the first round of the GNMCC series set for the first weekend in March.
"I didn't get much time to relax this year because I ran a training camp and also organised the inaugural Yamaha Taikorea 500 race in December. But I enjoyed it and wanted to give something back to the sport."
