I ordered one for my MT09 Tracer which has a Corbin seat. With me supplying some photos and some measurements they were able to make a custom cover and it fitted perfectly. Fantastic service.
I then did a tour of France in August 2020 over 2,500miles in all weather conditions. Including a dash back from Millau to Ouisterham when France was put on the amber list in the middle of the trip. 525 miles in a day and I really believe that the Cool Cover made it bearable even though it rained for the whole journey.
I think it is a fantastic product in any weather conditions.
