I have a modified 2002 Honda 400ex. The mods include: Sparks Racing 440 National big bore kit, Works shocks, Lonestar Racing A-Arms, swing arm, steering stem, axle, Maxxis Razr's, Douglas rims, Pro Taper SE bars, Renthal chain, Sprocket Specialists sprockets, AC Racing front bumper, nerfs, Maier blue plastic, IMS footpegs, tank. I think thats it. So my question is, should i sell my modified Honda 400ex and get a new Honda 450r and use the extra money from the EX to buy new performance parts for the 450r? Would the half way modified 450r beat my now highly modified 400ex?
