2 types of products are lined up: SS400 series with 120mm diameter, developed for big scooters with quiet and gentle image to match the large body of MAJESTY S, and R-EVO with 100mm diameter, which is popular for its light weight and racy design while maintaining quietness.
The internal structure of both of them is almost the same, so there is no big difference in performance between them.
You will be able to feel the preeminent texture that "this is MADE in JAPAN" in the making that is not overlooked to every corner of the BEAMS staff persistence by the complete in-house production in the factory while both are preeminent cost performance!
The sound volume is about the same as stock at idling, but if you open the throttle wider when accelerating, you can enjoy the powerful yet gentle sound and the pleasant power feeling that seems to extend forever
... Both are JMCA /, having passed stringent acceleration and emissions tests, and come with BEAMS' own two-year warranty.
It is especially recommended for those who prefer a more mature custom.
