Street Twin - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2020 Triumph Street Twin, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained Street Twin should fire up cleanly and settle to a smooth idle within a few seconds.
