Brutale engine to F4 750

Like the title says, there are lots of Brutale engines on Ebay, and since my 750 F4 needs a new engine, i was wondering what is the difference between them?

I have a good F4 750 head and gearbox, so if cams and gearbox are different between the models, i can change them from my F4

Has anyone done this?

The basic engine is the same ....... check gearbox ratios and cam part numbers to see what differences there may be.

I used to be fast....now I just dream about it.

I have been browsing through the numbers, seems there are some differences on the cams and box. But there are so many different models that its confusing

If and when it seems the bottom end is the same, i should be good to go with my transplant and parts mix.


Still would love to hear if someone has done this "mod".

The engine cases are the same, so the engine will fit. Primary difference from Brutale to F4 is in torque output vs HP...F4 is higher rpm/HP compared to Brutale.

Gearbox and primary ratios may be different. Cams probably but not the head itself (I don't think). Look at valve size for a clue there..

Intake cam has different number and pistons are different, also cam gears have different numbers. So it seems fitting the F4 head should do the job, just need to buy F4 pistons and put them on the Brutale.


Gona swap the box too.

Why do You think You need to change the head, pistons, cams or gear ratio?
Buy a 910 engine and put it in as it is, it would be torquier and will pull stronger.
And by the way You can trough the lower radiator in the bin and use the Bruties Oil Cooler instead.
But You would need to swap the Eprom at least if not the whole ECU.
Although as further I think might the F4 headers don't fit around the Brutale Oil Filter, Oil Cooler assembly.
And the Brutale headers might don't fit under the F4 Fairing.

Haupti, if the 910 would be straight swap without any electrical hassle, i would be tempted?

Silent, if you were in Europe, i certainly would jump on your engine offer. But shipping and customs from the US will be more than 1000 euros nowadays, thanks to certain Mr Donald
