ok i have a plus 4 axle and i think its a stock swingarm. im not sure i asked the guy that i bought the quad off of and he didnt know either. he said it looked stock but hes not sure. my Q is, is a stock swingarm good enough for mx or should i get it a little built more longer. thanks guys

you didnt say what year or/& style ..
88 style/length is good (shorter of the 2 stock lengths)..but like all stock swingarms they are weak so the question is not length,.... but stronger

yep, what dave said. the shorter swingarm is typically better for MX, its just a question of whether you'll crack it or not

yea its an 87. it looks strong but idk

The 86/87 swingarms were made of mild steel, whereas the 88/89 were made of aluminum. Also, the 88/89 were 1" shorter than the 86/87's, and are more favorable for MX. You can use your 87 swingarm, but for MX the 88/89 length is recommended. Then again this is all preference. Typically when you find aftermarket swingarms, whether they are the 86/87 style or the 88/89 style, they are the 88/89 length. Good luck.

Ive been using my stock 87 swingarm with no issues so far. Planning on getting a 450r swingarm for it soon though.
