Motorrad had more trouble than just rings. If I remember right the ring groove was cut screwy & twisted the rings so it never would seal up. I've not had much confidence in them since they started cutting corners, about 3-4 years ago, trying to eliminate machining steps, like not cutting the piston side reliefs at all or the lightening area above the pin. & that was just what you could see visually. This was on the cr500 pistons though.
The 90mm wossner I got on the other hand was machined inside & out , literally, weighed like 3 grams more than an OEM piston, & had the rings that capture the alignment pins. I like it, have to see how it last's but, so far so good

25+ years, and countless top end replacements using OEM cast replacement pistons. Not one single failure. Another negitive story that re-affirms my dislike for anything other than OEM.

plus 1 on that.

My experience with Wiseco has been perfect with no problems.
I have purchased 2 std K5 pistons for my 2K 5K and my 04 5K in the last year with no problems.
I have also purchased 4 other pistons for my employees bikes, Kawasaki 2K kx250, Kawasaki 98 kx250, Kawasaki 01 kx250, Suzuki 03 RM250.
While my experience is limited it does show that Wiseco can do somethings right :lol:
