It’s two hours for a minor service – change lubricants, check and adjust brakes, clean the condenser. and three hours for full, with all oils changed. More modern bikes are even more economical: change engine oil and filter, and check chain, brakes and tyres. An hour for a small service: £120. There’s no servicing that requires the engine out. Half of our early bike owners service their machines themselves, so don’t let that put you off a second hand bike.
