it would be cooler if i could get the proper black on yellow decals instead of the m3 ones it has on! from what i have found out the swinging arm is 2001 but i'm not %100. i will have to look if the mech hanger is replaceable. i have had this bike for about 3 years and its had hardly any use as i haven't got round to springing it for all of the 14 stone yorkshire man that pilots it!!! loving the decepticon decal on the orange frame by the way. nice bikes!
