SW-Motech PROマイクロWPタンクバッグ-4リットル防水。

Fit excactly
Well waterproof
Fit to sportbike and touched my chest (uncomfortable position) since i am fat 😁 when i tucked in for high speed.
High quality Build & looks tough

This is my review for this bike:

Pros:
* Waterproof: Essential for protecting your belongings from the elements.
* Good price for the materials: Indicates good value.
* Surprisingly spacious (for 4 liters): A small exterior with efficient use of space is a plus.
* Strong magnets: Secure attachment and easy removal are important for convenience and safety. The easy-to-use release mechanism is also a nice touch.
* Clear top pocket: Perfect for storing documents like passports or insurance, making them easily accessible during long trips.

Cons:
* Bulky for a larger rider on a sport bike: This remains the primary concern. Even a 4-liter tank bag can interfere with the tuck position on a sport bike, especially for riders who are larger. It sounds like this bag impacts your ability to achieve a full tuck, which is crucial for high-speed riding and aerodynamics.

Overall:
This 4-liter tank bag offers a lot of positives, including waterproofness, good value, clever use of space, strong magnets, and a convenient document pocket. However, the bulkiness remains a significant drawback for larger riders on sport bikes.

I hope this will help for others 😉✌🏻
