I'm helping out my brother-in-law put together a 89 exciter he bought over the summer, just wondering if someone knows the HP ratings of the exciter motors from '87-'91 steel liners and '92-'93 nikasil coated motors? Just curious how they would match up against the v-max 540 motor! THANKS!

I have owned a new 88 Exciter and a 1990 plus many Vmax's and for the most part the Exciter's usually holds their own from ~ 0-40 m.p.h. and then the 540 takes off and it's all over......

For the Vmax From my website with permission from Dyno Tech. I have a 1987 magazine article that shows the Exciter to be ~75 hp. so, Ramblnman is right !
