Here is the reinforced left hand bearing proposed by ATHENA for your HUSQVARNA CR, AE, XC, WR and WRE 240cc, 250cc and 500cc from 1984 to 1985 . This bearing is the exact size of the original which is 52.00x25.00x15.00. It is necessary to know that more the number of the bearing is high (c3, c4) more the bearing has play so that this one is not limited in turns. However, the more play the bearing has, the more it vibrates. It is therefore advisable to mount a C3 on a machine that takes 11,000 revolutions max and C4 if you want the engine to be freer to take these revolutions, if the engine allows it.
