A fair few people on here will testify to the effectiveness of the NEWER R&G crash bungs / frame sliders (however you refer to them). I had them fitted to the bike from new and the brackets on them are solid, chunky affairs. This is the thing that was changed from the old design from my understanding. There is NO cutting or modification to the lowers required.
My only further comment is to AVOID the OEM SUZUKI ones since the brackets for those really are hopeless - I've seen both since the dealer mistakenly fitted Suzuki bungs to mine before I pointed out on the order that they were spec'd as "R&G" quite deliberately.
Cheers,
Garry
