PROJEKT MOTEC KAWASAKI 250 ULTRA

Morning Malte,

To understand the differences in top speed, you have read our introduction, where the measurement method described. We always test each scooter with a full tank of all tests vs for things like Riva or other supplier that tests with 1 / 3 share a full tank. This leads directly to the scooter does not lift out and can only ride on the back-plate. Furthermore, we have a 90 kg test driver with Floatationjacket unlike up to a wet suit, and eventually will the salt water in the United States to get more speed than our brackish water in Stockholm.

How long we drove Kawasaki so we did not get more than 101 km/h, which was RIVA 104 km / h Factory Stock. Therefore, no limitation in the Super Course.
The Jestki is in very good condition and has about 30 hours on the meter.

In all the data we get from the tests, you can very easily break out the interval you want.
Want: 0-50 ? / 10-40 ? / 0-80 km/h? so it is easy to do.
You see the attached graph and can be easily read to you what you want for reference points

Is thinks clearer now Malte?

Enclosed a 0-80 km/h accelerartion graph

Nåt är fel på den där Ultran... Hur långt har den gått? Servad ordentligt?

Vad hade ni för maxvarv?

Niklas, i have read the graph befor, and that shows why a 0-100 time can not be used as accelleration statment to comare "befor" and "after" setups.

you can not make a 0-100 acceleration statment if the PWC only has 101 topspeed, because it is not related to the true accelleration.

in all car test worldwide ( on regular cars ) the show 0-50,0-100, 0-120, 0-160 accelleration, even the car has a topspeed of 212 km/h they never compare 0-200, because it is a useless time, just as your 9.9 sec of the ULTRA.

all stock PWC get tested 0-80 km/h (statment)for accelleration,

offcourse you can make accelleration statments like you want, but that 0-100 9.9 sec give a complete wrong picture. because all ULTRAS worldwide only need around 5 sec 0-100 km/h.
to test with full tank is also not so smart because the ULTRA has a very large tank compared to other PWC, so it would be better to test with the same amount of fuel to get true numbers. I dont want to be so critical, but it would be sad if no one take you serious after you have so good equipment, and spent a lot of time on the water

Hi Malte,

You have many points in what you write, but all of our reference projects, with acceleration in the range 0-100 km/h / 0-60 mph, and unfortunately so is punishing the weaker and more heavy-powered jetskis. Our major target group for our customers is + 60 knots, and when you pass 53.9 knots (100 km/h / 60 mph) relatively quickly and then get an acceleration figure is more comparable. If you want to compare directly between jetskis in different speedbands can be carried on a excel digit level or acceleration level in the graph.

But to quote you, when 2 different jetskis (different brand) have roughly the same top speed but it differs markedly in accelerations so describe it more the individual jetskis (engine´s) potential.

Best wishes Niklas

Ola,

Det här är verkligheten Ola, Riva´s tester är i stort desamma med skillnaden att det endast har i 24 liter bensin i tanken mot våra 80 liter, saltvatten och en relativt lätt kille utan luftmotstånd (Vi kör flytoverall och de maximalt våtdräkt)

Men att du fick upp din Kawasaki i 62 knop STOCK LEGAL från utgångspunkten 54,5 är 7,5 knop förbättring. Jag har aldrig stött på någon som varit så duktig att få fart på en Kawasaki förut.


Härligt jobbat!

Mvh Niklas

Ingen tvekan att Ola är duktig och extremt seriös med sitt åkande.
Grundfarten på en helt original Ultra 250x är ju faktiskt mycket varierande på vilken maskin man får, min gjorde 57-58 innan mods och 61.5 efter rideplate, intake och tändnings-fixande.
Så 62 är inga som hellst omöjligheter.

Men det blir mycket intressant och se om det blir några skillnader med Motec-sprutet, mina gissningar är att det inte händer så stora förändringar på toppfarten.
