Got a lead on a M750 for a possible Scrambler project. It's the later engine case carbed model with about 25,000 miles. A '99 model in good condition and some nice extras.
The project is to fit TKC 70's and a few other bits and bobs to run around bad paved roads and good dirt roads. What are the strengths of the 750? Been a long time since I have tested one. Besides the obvious lack of torque and wet clutch compared to a 900, are there strengths for this application in mind? Fuel economy, smoothness, less weight?
Cheers.
My M750 gets low 50's mpg.
A bit lighter than a 900, but not much.
Small cases are about 12mm shallower, so more ground clearance.
I have a skid plate that will fit a small motor... as long as the oil cooler (if it exists) doesn't interfere.
You can look forward to a really flat, broad torque curve.

Got a pic? Pm me [thumbsup]
I've got a '99 M750 and I can't say anything bad about it, it's got nearly 50,000 miles on it and the only time it's left on the side of the road is due to a corroded ground cable. I'm sure a 900 is a hoot to ride too. I average in the mid 40s for fuel economy no matter if I'm riding it like I stole it or just puttering about town. A couple things to keep in mind on the carbed ones are carb maintenance, I had to do the carb diaphragms and the emulsification tubes at about 30K on mine. On the good side of that, they have the same diaphragms as a DR650 and those are about a fourth of the cost of the Ducati slide/diaphragm assembly. As far as smoothness, I can't speak for the 900 but my 750 pulls hard and smooth from just a bit off idle to redliine.

Thanks fellas.
I have read and been told that the 750, while lacking the sheer grunt of the 900 is a smoother, sweeter running motor. Has this been your experience?

Mine ran kind of rough. Also the headlight fell out when I jumped it. Make sure the headlight is in there tight. Otherwise I liked it, especially after I raised the suspension and lowered the foot pegs.
In my opinion, the 750's sounded better than the 900s.
Today a Daughter told me she will share in a Monster with me when she gets her full licence. In light of that maybe a 750 is a better choice.
I never owned a carbed 750. I had an injected SS.
I didn't find it smoother, lighter, or anything except slower than a 900.
Fair dinkum? Wow. Not a lot justify it over a 900 except price.
I hope to test ride Nibor's Nugget when it's done (it's 90% there). Nugget is modified so not a good comparison.
On reflection the softer power of a stock 750 would be better for a newbie coming off a VTR250.
Is the 750 wet clutch easier to use for a newbie than the 900 dry clutch (as in smoother)?
Yes.
Howie, do you have a view to the relative smoothness of your 750 compared to your big bore?
The wet clutch on the 750 has a smoother, more consistent engagement and will stand up better to nubee abuse. Supposedly less strength needed, though I don't see much of a difference on the 750. Noticeable on the 600 and 620 though. The only real negative is they are more prone to clutch drag when cold. Gotta say I do love my dry clutch though.
Thanks.
Did you find the motor smoother than the big bore? DP didnt, but a few blokes have told me they found the 750 a particularly sweet and smooth engine with less lumpiness than the 900.
I love how easy the dry clutch is to work on. The one M1000 I have ridden was quite smooth. You could sense substantial crank mass smoothing things out.
I wonder if riders notice a difference between the small and large alternator 750 models with the difference in crank weight ?
Smoother at lower RPMs, over all I think my 1000 is smoother. Of course, tune makes a big difference

I had a 900SS dry and the clutch was I guess 'snappier' than the wet clutch on my M750. Also, I've got 45,000 miles on the original M750 clutch and I was putting a clutch pack in the 900SS at 18,000 miles. So they seems to be some wear differences for sure. I can't rule out rider error, but I'm 39 and have been driving with a clutch since 12 years old so I've not a clutch idiot.
Tune does make a difference, my M750 was jerky at slow speeds, the 900 was not, but some carb adjustments on the M750 really cleaned up the slow speed stuff. Sure it was definitely slower than the 900, but the M750 properly set up is pretty pretty much a smooth puller from twist to redline.

The 900 won ;D
Hahaha it certainly did 😠You're more than welcome for a ride regardless!
Having come from a vtr250, as long as she's got plenty of experience under her belt, the step to the 900 is really not that much more than that it the 750. Either way, she will adapt as she goes, it's human nature.
I would have thought the 750 would be ample for dirt/rough roads, you wouldn't really be using the extra few ponies on the brown stuff?
I was looking at 750's, but this one came up and it's like an old friend since I have done so much work on it. It seemed inevitable as if fate had taken hold as she just kept coming back to me.
I could see my daughter on a 620 or 750 and you're right, the VTR250 will be plenty for quite awhile.
About time we got an update on nugget.
