The price listed on our website is our best estimate based on current information from Hirth. Because these engines are imported from Europe, the final cost can fluctuate due to exchange rates, international shipping, customs, and tariffs.
While the listed price is generally sufficient to place the order, Hirth requires payment upfront before processing, so we cannot determine the exact final landed cost in advance. As these additional import-related charges are outside our control and remain the customer's responsibility the website price should be considered a close estimate rather than a guaranteed final total. Shipping takes approximately 60 - 90 days.
