If your into hillclimbing let me know always looking for new guys to climb with . I used to have a 10Mil serval and 10mil cheetah both worked awesome but lots of $$$$ both setups were extended swingarm and widened. As for recommendations for cheap or kinda cheap anyway . +2 arms and widened axle with +4 swingarm works good everywhere!! Motor stock motor with pipes will climb good just not as fast. If you port motor a low port timing high compression motor is way easier to climb with than a high strung drag setup. A serval setup works great. It more money. A cub takes more rider work to climb with but can also be faster in some areas but you need to be more aggressive when riding. Any of these setups will be a fun all around quad. You can go longer on the swingarm but then not as good in trails. And requires better tires which cost alot$$$ In the video I'm going to post is mile hill and centrailia and the blackie we ride I'm on the white and green raptor my son is on the white and red banshee that's a 4 mil with stock non ported cylinders and cut domes no where near setup to make power to its full potential and geared down still from when I had it set up for my wife. Needs more gear but it works with my 14 yr old son well so I leave it he goes fast enough lol That's a low compression pump gas setup with t5 pipes extended a arms plus 4 swingarm and old dombo paddles. We ride these quads all over the mountain with no issues. Hope this helps any questions feel free to ask. Sent from my iPhone using Tapatalk
