"It is about fundraising as well as raising awareness of what the SPCA does," Wawatai said.
"So the more we can get along for the ride the better."
For that reason, to cater for the lower-capacity model motorcycles, the club has devised a "scenic mystery ride" under 100km, which he estimates will take about an hour and 20 minutes to complete.
"Got to think of the smaller bikes."
He will don the gear and climb aboard his Harley-Davidson with his pillion passenger — Baxter.
About half a dozen other local riders and their canine passengers will also gear up, along with visiting riders like Gary Anderson, from Taihape, who will bring his dog Cairo along for the outing. Cairo rides in a sidecar.
"A ride for our furry friends," Wawatai said.
• The ride, which has a $20 registration fee per person, will set off from the Napier SPCA in Mersey St at 10.30am after a 9.30am "meet and greet" and return there at the conclusion for a barbecue run by SPCA volunteers.
