The TQ engine crank will be a direct drop in for the MR ninja.

The other alternative is to find a used one. I'm sure someone has to have a dead GRP lying around with a good crank.

That is the crank from the sport version. I'm not 100% sure it would fit the tuned rod. Give A-Main a call to double check with them.

It should work fine. I can tell from experience though they are nothing alike as far as the way they are cut the MR ninja cranks are much more aggressive than the sport crank. I'm not sure about the GRP tuned crank though.
