This is a good quality,strong kit.
BUT... It will not work on the Honda st90 or the Honda cl90. They have a unique motor case that differs from the ct90/ct110.
I hoped it would work for the st90 but there is no possible way. I'll stuff this lifan into a ct90 I have with this kit instead. This is not flimsy steel!! I was concerned it would be weak but it is very stout. If your looking, it's worth it
