| I have a 851 SP3 and a 916 Bip - the SP3 feels much livelier than the 916, turns in quicker, and the cast iron discs are very effective, although some say a radial master cylinder is worthwhile. the SP3 and SP4 are mechanically virtually identical, except the SP4 lost the ally fuel tank and a few other light bits, so is a bit heavier. Appearance is just down to taste - they both stand out from the 9xx/748 bikes.
