Rider Profile

Best For	This custom-tuned triple suits an intermediate to experienced rider comfortable with sharp, responsive handling and a one-off seat lacking stock refinement.
Purpose	Built as a Yard Built special by Wrenchmonkees, it's designed for spirited street riding and showcasing bespoke style rather than long-distance or utility use.
Rider Fit	The 830mm seat height and lightweight, aggressive stance demand reasonable rider confidence and fitness, with minimal wind protection or ergonomic cushioning.
Character	A raw, characterful streetfighter-scrambler hybrid with punchy triple-cylinder power, sharp steering geometry, and premium K-Tech suspension for engaging backroad thrills.
Not Ideal For	This is not the bike for riders seeking touring comfort, passenger accommodation, or serious off-road capability.
