The std 300 Beta in stock mode is weak. Beta used to have a bunch of factory parts to make it zing. My son had a 2015 with all the goodies and it was a beast. On the other hand I spent a day riding Ray`s bike and it was a monster, but was quite fun! If you look at the stock plate on the left, you can see the witness marks were a few springs moved off center. Just because you use different springs does not mean they don`t work correctly. The Japanese put alot of thought in the aftermarket parts they use.
