I was on a ride when I personally witnessed a Hyo 250, being ridden at a steady speed, on a straight, flat road at less than 80km/h snap a chain and leave it's rider in the awkward situation of delaying a group of 8 riders while we waited in the middle of bumfk nowhere for him to be towed to the nearest motorcycle shop and have a new chain fitted.
It's sad to hear that you have lasting pain. that sucks. However your pain might not be as a result of a bad bike.
I suspect that your well-meaning and obviously supportive dealer made an honest mistake. Maybe even a few of them.
OK, so the chain, maybe it's a mistake on their dealer's part, maybe not.. BUT..
Bikes are shipped without the battery fitted. The battery is under the seat. A seat that the dealer would have had to remove to fit the battery and re-fit afterward. If your seat was fitted poorly, then there's no one to blame but the dealer.. Even if they did fit the bolts before the initial shipping, the seat is once again removed during the 1,000km service. Was it re-fitted as it should be, or was a stoned 1st year apprentice responsible for that? Either way, your dealer HAS dropped the ball there.
As for the master cyl. Yup 100% Hyo's fault. Simple solution and yet they've never bothered to issue a recall for what is quite obviously a safety issue.
It's been the story of Hyosung's existance. Iffy product quality combined with small-time dealers who are often defensive about their failings and are quick to blame anything other than themselves. Hyosung also have a tendancy to accept any cowboy that's willing to sell their bikes as a dealer. I'm not saying your dealer is a tool, but they've laid the blame for some of their failings at the feet of someone else rather than accepting that they've made a mistake and get on with fixing it.
Even Hyo Australia's main distributor are guilty of this. Stigger's story is more shocking than most. The pictures he has posted are very damning. Graphical evidence of the catastrophic FAIL they did on rebuilding his engine.. It's one of the worst examples I have ever seen of an organization with zero pride in their work. Evidence that the employees could not give a flying firetruck about the work they output. The "She'll be right mate! It's only a bloody Hyo after all" type of attitude. This is the reason why I do all my work myself now and every time I did have to go back to my dealer,when I got my bike back I would check everything I could think of.
I LIKE my dealer, but they've made some pretty shitty mistakes. My rear tail light needed replacing and they broke my license plate light while doing it. A fact they of coure didn't mention when I collected my bike. I didn't notice it until it was pointed out to me by another rider who was behind me.
"Professional" means "Paid to do it", unfortunately it doesn't always carry the meaning and significance that we as consumers assosciate with the word.
Hope you get well soon! Ohh and just to complicate matters a little. I wouldn't buy another Hyosung either. Nor would I advise anyone who asked me to get one either. Enjoy the Zookif you go down that path, but don't expect it to be perfect either.
I'm going out on a limb here and might take fire with this comment:
Yamahas are better.
