I purchased the Acerbis Rally Pro X-Strong Hand guards after reading all the reviews. They look great and took a hit from a good size tree and held up great. Plus saved my hand! Highly Recommend these.
The Rally Pro X-Strong is a durable injection-molded nylon composite handguard that features an anodized aluminum bar for ultimate protection. It includes an indexed steel bar-end insert that mounts solidly and will not allow the guard to rotate in a crash. The included X-Strong mount kit allows the protection to be mounted to the handlebar with plenty of room for cables and brake lines. Optional spoilers are sold separately.
