IT depends. I have a NWS hugger. Things to consider other than chain guard when getting your hugger.
1. type of mount, do you need to make your own holes? (jerry riggn)
2. Do you have to paint it yourself? difference if prepainted?
3. The part over the tire, square or rounded or pointed? look you need to consider.
4. Does it SIT ON THE SWINGARM (upperpart) or does it mount below the swingarm. Thus preventing crap from getting upinto the shock area. Alot of them sit ontop of the swing arm and have the R1 look and is more a fender then a hugger. Doesnt do anything to keep the crap out of the guts area. The NWS has a tight fit and extends below the swing arm. Keeps it all clean.
5. How close to the tire will it be. Too high up or further away from the tire = more flinging crap to clean off your undertail. Also looks cheesy. Just as a measure the NWS is almost less than a #2 pencil thickness away from the rubber. (tight) makes tire look beefier too. IMO.
6. Whats it made of ABS plastic which gives a little more and is durable, or fiberglass resin which pretty much cracks under duress. Or Carbonfiber?
7. The chain guard is kinda last. Even if it comes with an attached chain guard and is ABS plastic and NOT painted, you can cut it off, sand a little, prime, paint and use your own and get the best of both worlds. Might pay a little more due to painting but you get what you want.
All worthless opinion but those are the things I consdered before I decided. Ended up with an attached chain guard and I like it.
