The durability of classic British engineering was put to the test last weekend as a group of Triumph motorcyclists converged on Whanganui.
Around 35 riders came from various destinations around New Zealand on their pre-unit motorcycles to spend Saturday night at the Grand Hotel.
Pre-unit construction, also called separate construction, is motorcycle engine architecture where the engine and gearbox are separate components with their own oil reservoirs, linked by a driving chain within a primary chaincase.
"Pre-unit Triumphs were made prior to 1962," said Triumph enthusiast Joe Hannah who travelled from Kaiwharawhara north of Wellington on his 1950 Thunderbird.
He has owned the bike for over 30 years and is a supplier of parts for pre-unit Triumphs and other classic British motorcycles.
