PERFORMANCEHASACOST

The inlinefour engine is drastically oversquare and uses offset camshafts, finger followers (rather than bucket and shim) and heady revs for a claimed 194bhp. You’ll get more than 180 real ponies at the wheel. This means it needs looking after. Bikes should have had services at 6000 and 12,000 miles, then a valve check, plugs and fresh fork oil (with a £650 bill) at 18,000. On top of this there’s supposed to be an annual check, too. History is essential for assured longevity.
