you should not forget about new fork, cause the DJ 3 is too heavy and it allways pushes down the front of the bike. Then there is many stuff to change cause of weight, as you wrote you would buy one for 4x...
yh i was thinkin about gettin some pikes for it? but i also want to use the bike as more as a mini dh bike would it be strong enough and be able to cope with it?
