I have been maintaining my Suzuki Sprinter since 2013. I always used Genuine PS spare parts and it really paid me back, always happy.
Recently, it was serious disappointment for me. I replaced Sprocket set and clutch/pressure plates and they are pathetic in quality n performance from the day 1.
For clutch, there was no pick as it should, plates slipping issue, initially I used PS oil and then Liqui Moli which I have been using for 3 year now. With LM there is some condolence.
For sprocket, there was jump in chain from the day 1 as if I have put a weak/de-shaped rear sprocket. My mechanic tried a lot but the quality is pathetic.
Both sprocket and clutch work was done by the same mechanic. So I have zero mistrust on the workmanship.
I got indicators and reflectors and they also sucks big time in quality. I also did get them 3 years back and still I have those, the quality difference can be noticed by anyone.
I not saying that every spare parts quality sucks. What authorized dealers and my authorized mechanic told me that the parts which are manufactured locally, they are crap and even China copy is much better.
So I would recommend, do not lose extra bucks. Do your survey and then decide.
