Just looking at a proshark 90 for my son. First off do you need to run anything over 93 high test in these? And how are these holding up to normal trail riding,and might try him in some racing either mx or flat track.

 

These bikes are great for the trail. No you dont have to run 93 oct. in them they will do fine on 87 octane. i do suggest to get one for your child.

 

thanks for the info. Do you think I should hold out for the 07 year models, heard they had alot of improvements?

 

Yes for sure get a 07. They are out now and have a ton of improvements. I have and 06 was nothing but problems so they made these changes for a reason.
