Of all, RXZ is most cheap and problem free, and maintenance easy, and can go quite fast too. Cost abt $5.8K. Insuarnce 1st party $300+. If u don wan hidden cost like GST and what lan jiao fees and all that, i suggest u go "ASPHOON" motorshop buy, they just charge u the bike $ and yearly interest that all, no other fucking charges. (Thats gd abt this shop) and its along Serangoon Road, opp the Civil Defence camp. website is
www.asphoon.comSP/TZM both fast bikes. and looks more fierce and sporty. Depends on individual lah. But if me, i buy TZM, not so TAXI, and its cheap to maintain and modify.
