Hey mate, I wanted the kl71 but they had none in stock for months back then.
I like the look of them aswell,and was sure what spare to get cause of the directional tread...
So got the couragia and they seem fine.done 5000 k so far. Ucan feel the tread lugs at lows
Speeds up to 20kmh and a bit of noise round 40 to 50kmh. But nothing above that.
See what other responses you get. I know lot who run kl71 with no problems and only ever meet a few with the federals.but no bad reports.
Good luck with ur decision
Done 10,000km's on Khumo KL71's and very impressed with their performance on and off road. Very quiet on road for a mud tyre and handles wet tarmac very well. Off road they have performed faultlessly thru mud, rock and sand. Will buy the same once these need replacing. Highly recommended.
