Great job, converting torgue figures into coordinates will be so much easier with your tools. Only thing is that Iam not so sure 125 Cup bike is the same as 125 GP. There should be more diference then just low RPM torgue. Back when Piboso had the bikes stats on the website the diference was about 5-10 HP

You're right about the difference in power between the Cup and GP bikes. I made a stupid mistake. I have fixed it now. Sorry about that.

Here's the Excel file I used to create the dyno graphs for all four bikes including raw data:

Edit: Excel file contained an error. Now fixed.

That's true. I only wanted to do a quick test to see if it worked. Bike's a lot of fun

Ok that works. I just doubled the "MaxTorque" setting. No more slipping. Thanks.

Cool. Thanks. I'll try that now.

For a 250 just double the torque figures for the msm 125 figures. A 250 twin is just two 125 cylinders

I just doubled the torque figures on the msm 125 rr to test it. Its quite realistic because a 250 engine is basically two 125s. The problem with the bike is that it rides like the clutch is slipping on full throttle. Not sure how to fix that. Any ideas?

Here's the engine file:

Since most dyno charts show torque in foot pounds, multiply newton meter figures by 0.7376 to get foot-pounds.

Nice!

I've been working on this:

I multiplied RPS figures in engine files by 60 to get RPM then used the formula below to calculate horsepower:

Horsepower = (torque X rpm) / 7120.9

Interesting. Thanks.

I thought I'd just post a pic of a quick chart I made in excel for the varese v594 torque curve:

The ENGN file defines the on and off-throttle torque curves. The units are RPS and Nm ( will probably be changed to RPM in the future ).


What does RPS stand for?
