Is motorcycling allowed?

Interesting, nobody wants to touch this bike of mine so we decided to give it a go ourselves.

Burned wiring on the stator, there is the culprit. We took it in for a proper rewinding, so ETA is next week.

Not sure if there should a bit of play on a flywheel, see video for reference: 

 

You can clearly see that the previous owner rode this bike hard/did not look after it if you look inside of the flywheel:

 

Looking forward to seeing your project go ... please do take lots of pics and document the work here!

@Hairy on a Davidson I'll try my best, I am still a noob to the world of motorcycling. But hopefully we can sort this bike out so that she can experience some off-road adventures!

From My experience in the BM moto world, its be st to get to know your bike yourself, use the interwebs for info and sort it yourself, to save lots of frustration and cost.

Try advrider.com, not sure if they have the 4fiddy bmxes dedicated subforums like they do with the other bms , but there is a whole world of knowledge on there that  may just give you the direction and answers you are after.

nice bike, I have a thing for BM motos that started with the funduro back in 94…

Indeed, I agree with you and then you can hopefully put that knowledge to good use if you experience any problems out on an adventure.

Thanks for the tip, I am currently on the Wild Dog Forum whereby I am pointed in the right direction since a few members have own a G450X before, so making progress at least.

For the small time I spend on it so far, I also climbed off with a smile on my face, so eager to get it back up and running.

Are you referring to this model perhaps:

What's with that front /rear tyre combo? Did the previous owner supermoto it?

To the renamed fella now proudly mounted on a Davidson, I have to say I'm loving your new avatar, identity and obvious pleasure and enthusiasm on this new lifestyle of yours. It's great to see it finally come to fruition.

Couple of interesting things around the G450X - the swingarm pivot is directly in line with the front sprocket shaft - the theory there was that they were trying to keep the chain tension absolutely constant by pivoting the swingarm on the same fulcrum as the front sprocket - that meant they had to have a really unique rear suspension design too.

Also - the engine is full of oddities - the clutch is mounted directly onto the crankshaft so it spins super quickly and if I'm not mistaken, the engine also runs counter-rotating to the wheels - so that you had less momentum when slowing down and turning.

Jade Gutzeit raced one in the Enduro class - I think he was marginally successful, but he wasn't overly complimentary.

I also remember BMW were super strict with the warranty - even putting on an aftermarket pipe voided the warranty.

Oh and the motor was made by Kymco - which we at Yamaha used to regularly remind the BMW boys whenever we had a chance!

So the previous owner used the bike a bit for commuting, so mostly road and maybe a bit of gravel over the weekend.

It is an interesting combo but my plan would be to get 50/50 on the bike after these are worn out.

Very interesting, thanks for the share!

Oh be still my bleeding heart!

Side note, that bloody contractor had the trailer hitch bearing on a empty plastic paint bucket. As we approached the fooking thing to look at the plans, the bucket collapses and our engineer and contractor standing near the hitch realise that (1) they could have been in a world of pain and (2) the contractor eases knowing he has a proper set of safety boots and the engineer goes pale wondering just how protected he would have been with his thin pair of vellies.

Sounds like a typical German solution to a problem that did not exist!!!!
