Forgive me for not searching I am sure this has been coverd but between my dial up, old computer and this slow site if I try to search I just get booted off of the internet. Trust me it suck's. Anyhow what is the diffrence between the two? Is the I.A.S. thing really worth the double cost? I ride every day and alway's ride solo. Iwant to upgrade from the stockbut if I dont"have" to spend double I dont want to. Again sorry for thelack of searching. Thanks in advance.
