舊式的乾式普利珠設計常常會因為潤滑黃油的滲出，導致傳動部品的打滑，輕則影響傳動效率、減少皮帶壽命，嚴重時甚至會影響行車安全。有鑑於此，日本BANDO與其合作的日本車廠，共同研發出乾式普利珠。新型的乾式普利珠，現在已經是各大車廠所泛用的規格，擁有多年的普利珠設計製作經驗的BANDO，擁有許多獨家設計。

Due to grease and lubricants our old style of Wet weight rollers often caused parts to slip, impacting transmission efficiency, belt life reduction and even riding safely. In view of these problems, Bando with the cooperation of a major Japanese motorcycle manufacturer ventured jointly into developing a new type of Dry weight roller which is now the most used specification. Bando has 100 years of experience and exclusive designs on weight rollers.
