Product details
The SMK Allterra Bulldozer is an adventure-style motorcycle helmet aimed at riders who split their time between sealed roads and dirt. Built around the Allterra platform, it combines a full-face shell with a removable peak and an internal drop-down sun visor, making it a practical choice for long-distance touring and dual-sport riding.
The Bulldozer graphic gives it a distinctive on-road presence while retaining the functionality that adventure riders need day to day. Available in a range of shell sizes to suit different head shapes, the Allterra Bulldozer is positioned as an accessible entry into dedicated adventure-touring protection.

Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
