Does anyone have an opinion on Emgo filters for bikes? My son is getting into street riding, and he has purchased an 02 SV650S. Pretty sweet bike, IMO, good handling characteristics, powerful enough to get out of trouble, without so much power and looks to get into trouble. A nice sport touring bike. 18k miles, PO was a very detail oriented guy; the bike was well maintained, and had lots of extras: hard bags, heli bars, scottoiler. Emgo makes two filters, a generic OEM replacement, and an upgraded line called Micro-Tech. Factory blurb indicates anything above 10 micron is filtered. Filter feels heavy, looks to be well made, better than the OEM Suzuki replacement by feel alone. Fells a lot better on the wallet too... nearly 5.00 less than OEM. Any opinions, or experience with this filter line?
