WHEELS & TIRES

As a tire size, the front (OEM) you need is 120/90-10 and the rear one is 130/90-10 and don't forget to be able to install a rim kit (Fatty) (12x6 or 12x8) on your Yamaha Bws'r/Zuma 19988 to 2001 or MBK Booster, you must ABSOLUTELY have the TNT Vertical rear hub , with an MXS adapter (4x110) to be able to install on the rim! 

And as for the 12×4 front rim, the Ruckhouse 4×90 12 mm hub works perfectly, with a 4-piston Adelin style disc brake !
