Something many people do not is that not all the 900 Ducati engines are the There are five different specs that I know being as follows :

The best came in all 91 to 97 900 SS and SL bikes. These were also used in 900 up to engine number 037727 ( 1996 build ) and the 98/99 900 Special.

The not so good carb came in 900 Monster from number 037728 and the Cagiva series. The differences are camshafts and These lower spec have 750 cams and valves. The are a couple of mm smaller. The cams are a wacky, being about the duration, but lower lift the good 900 cams, with timing, much wider separation and less overlap.

To my mind, they are an old cam design, out by the part number beginning 0370, indicating something the early or mid eighties. The inlet and lift is almost the same as the 4V cam. Now that I think it, the exhaust is similar to the 4V exhaust

As far as I am concerned, the only thing cams are good for opening is the bin as you them away. Riding 900 with the detuned engine you wonder what the hell thought they were to achieve. It does explain, why the Elefants always felt for a 900.


3 engines in series ( maybe 4, as the fuel Monster engine may have gearbox ratios to the SS. The cams are the though. ), with cams the main difference.

To get the wacky one out of the way The 900 ie Cagiva Elefant of 1990 had a injected version of the 906 engine, but a 5 speed gear box. At the only one I have ever did.

Not worth worrying about too I don’t even care cams are in this one.

The powerful 900 2V in standard trim, the new SS / engine has longer duration/higher cams than the carb SS Apart from that and the I believe they are basically the I could be wrong, but it’s not enough to me to go and make a detailed

The cams are very similar to the ST2 although the ST2 cams have a more lobe separation, for a less overlap.

Obviously having a go at Cagiva for the the engines supplied for use in the Gran appear to be fuel injected of the old Elefant engine, with the cams and small valves. certainly feel that These engines do use the Weber 1.6M ecu though, as opposed to the ecu used in the SS / Monster.

On this you have to award the win to Cagiva. a little, I am fitting some 900 SS FI to a Gran Canyon in the near so we will see what the change Should be an absolute hoot, the way our shop 900 SS FI goes.

A dyno test has shown a std Gran Canyon makes 65 Hp, 13 down on the injected 900SS it shares everything, but the heads and with.

So there you have it. If you a late model 900 Monster, the mod to make is getting rid of the standard and maybe the valves. This you behind the eight ball the start unfortunately. I have one of these Monsters with a 944 kit and a jet kit and not believe just how slow it It was only when I checked the date that I realised was wrong.

It felt much the same as a early model, maybe a little slower. Not what I expect from a 944.
