The Sertao's stock shift lever is a cylinder that's 18 mm diameter and only 25 mm long. Adventure boots make it difficult to reach this very short shift lever because the crash bars interfere with reaching a foot position close to the bike to use such a stubby shift lever. The Hornig lever slides over the stock lever and is attached via a single set screw. It's 60 mm long (great!), but it's width is awkwardly large at 30 mm, so nearly twice as wide as the stock lever and wider than the OEM's is long.
