Peaky stroker twins, more go than looks. Dubious small-ends, pistons, oil pump and main bearings. Handling degenerates when s/a bearings go after a few thousand miles – chassis easy enough to upgrade. Disc, paint and electrics rot. Hard use means engine often melted down after as little as 20k. Need frequent engine tune-ups.
