JB4 MAGTAN
JB4
JB4 released in 2008, was derived in a continuous trial and error process and is the unstinted result of all our research & development, know-how, and wheel technology since the debut of MAGTAN in 1999.
Although it is the lightest publicly available MAGTAN wheel, with its ideal balance of high rigidity, excellent impact and corrosion resistance, road-following ability, and appropriate elasticity, JB4 proudly positions itself as the ultimate commercial race wheel.
