:hat I have just recently been to Red Dog Motorcycles to ask about potential clutch failures on the Tre. It turns out that they have two in the workshop that have failed.
The problem is not the actual clutch basket but the drive gear riveted onto it. The small gear breaks up, leaving the bike free wheeling and fills the oil pump causing failure of that also. This can leave you up to £1000.00 out of pocket. The other problem is that you can only rebuild the engine using original Benelli parts, thus potentially having the problem again at a later date as there is no modified unit.
You will know if you have a problem if the clutch becomes very noisy or you lose drive. You can also check your magnet on the sump plug, if this is covered in swaf (like a christmas tree) you have a problem!:rolleyes
If there is enough interest, I will try to contact a few engineering companies around my area (Kent) to see if it is viable to have some machined. If so it would mean having your existing clutch removed, the basket taken off and re-riveted onto the new gear.
I don't know the costs obviously, but if there is enough interest the cost would come down. Please let me know if you are interested.
