Yeah, laying her down was what I was told too. But that was back in the 60s & was wrong even back then. It was the thing to do when the bikes didn't have very good brakes. And a lot of old school choppers ran no front brake, Indian Larry was one of many.
But the first time a lady backed out in front of me, I laid 'er down just as taught. I remember thinking as I slid down the road, that was dumb, I could have stopped. And whether I hit her or not, this is an accident. I HAVE NOT laid 'er down to avoid an accident since 1967. I haven't been in a wreck since 1968. I've had close calls, but practicing emergency braking & evasive moves has paid off MANY times through the years.
An engine guard usually only helps in a low speed tip over. They are not meant to do anything in a real collision. Most don't attach to the frame well enough to offer any real protection. In some cases, it might even do more damage by trapping your foot or leg.
That being said, I have one on my new bike. I don't have one on my Savage but if I did it would be the Wingerline? style. The OEM one doesn't even make a good place to mount hi-way pegs.
