bgm 60 mm Vespa PX shaft -Race

Racing timing - but correct!

With the bgm PRO Racing Wave there is finally a racing wave with reasonable timing. The times are 110 ° opening before top dead center and 65 ° closing after top dead center. This finally puts an end to the annoying blowback and the better filling can also be converted into performance. The inlet area of ​​the rotary valve cheek is flow-optimized and polished. The width of the rotary valve cheek is 17,4 mm, making it the only shaft on the market that offers the option of milling really large areas using the rotary valve control.
