The M1100 range are the last of the air-cooled Monster models and represent what many regard as the pinnacle of the engine’s development. The motor is an absolute peach with a stonking midrange, while the chassis has inverted forks and radial brakes. Watch for The finish on the aircooled engine can be poor and start to flake. Also ensure the bike has a good service history. Price range £4500 to £7000 If you love Galluzzi’s classic Monster look but want a bit of fire, the stunning S4RS is the Monster to buy. Raw, aggressive and more than a bit wild, the RS not only looks amazing, it delivers in terms of performance, too, thanks to its Öhlins suspension and Testastretta motor. Watch for The 998 engine has several quirks that need to be kept on top of, so a full service history is essential. Price range £6000 to £7300 This model is often overlooked, but is one of the best of its era. The S2R comes with the 803cc engine, which makes it more gutsy than the smaller M600 models, and then wraps it in an achingly cool look thanks to stacked pipes and a single-sided swingarm. Watch for As well as service history, check the eccentric adjuster on the hub isn’t seized. Price range £4000 to £5000
In 1993 a M900 Monster cost £7500, which was £400 more than a Honda Fireblade!
