Neither one by themselves provide the protection needed (upper + lower). With the SW Motech Engine bars, one also needs sliders for the left-side engine case as well as for the right side engine case. Upper protection is pretty good with the SW Motech bars; however that is for a zero speed drop. For slow speed drops, the Triumph handguards along with the engine bars provide better upper protection. Axle sliders for the front axle are a wise investment also to protect the front fork in case of a low speed drop.
Good frame sliders are as good as most of the engine bars; however, they cost more--but there is NO vibration created with them. All of the engine bars create some vibration with SW Motech creating the most, IMHO. I pulled mine and sold them to a member on that other forum after posting exactly why I was selling them--VIBRATION...if I wanted a vibrating Hardley, I would have bought one.
I bought GSG frame sliders (from Twisted Throttle) and a right side case slider...I made my own left side case slider after a low speed drop which ground the case down a bit. I could't find the GSG frame sliders for the Tiger 1050 on Twisted Throttle the last time I looked. A pic of the left side should be attached. A pic of the right side is in the last post of mine on the Remus PowerCone thread: http://www.triumphrat.net/tiger-1050...s-exhaust.html
