(Above) Freddie Spencer chases Martin Wimmer in Belgium. Spencer's RS250RW is nothing like the for-sale RS250Rs, with a completely-different
engine based on half a 500cc V -four; bore and stroke is 54x54mm f or 249cc on Freddie's. vs . 56x50mm and 247cc; crankcases on Freddie 's are one-piece
with a quick-change removeable gearbox vs. the RS250 's bolt-together cases which must be split to change gear ratios.
Note RS250RW's (below ) ignition w ith li ght er flywheel vs . RS250R's
(above) external rotor. ATAC system looks similar, centrifugally operated.
