Question Knobby Tyre Horror Show???

Hi Folks,

Just swapped my RNineT Sport for the Scrambler-X and am hearing a whole hose of horror stories about the knobby tyres. Why are they so bad? or are they not as bad as suggested?
Cheers - Gentry

Karoo 3 tires:
I don't think they are bad, I really like them. The sound a little more when riding on asphalt but there is no problem with the grip. I have used them from below zero up to 30, dry and wet. Many talk about slow and vague steering, perhaps due to low tire pressure? or what kind of motorcycle they are used to ride. They area little twitchy riding really slow other then that I have no problem riding them all the way out to the edge of the rear tire. They work good on gravel roads but not the best on mud and snow/ice... I dont think I will get that many miles on them... I have 3500 km on mine and I see alot of wear (perhaps what you have to pay when you get grippy tires).

If you plan to ride only asphalt dont put on these for the looks, go for an other tire (Perhaps the Metzeler Tourance NEXT)

During the first few miles I was concerned - on top of the normal trepidation with new tyres the steering behaved differently to what I was used to/expecting. I ride a lot of bikes so familiar with different feel but this was different...after about 100 miles I got used to it and now feel confident and clear about what it's doing and what I need to do. It 'understeers' but it's predictable and am really happy with mine.

I would say that I think it's probably not a good setup for a novice but fine for anyone with some biking experience.

Hi!
Could you help me what you mean by "- It 'understeers'". I know in car "terms" what I would call understeer but dont know what to expect of my motorcycle .

I am not trying to be a person looking down on you, I ask because I dont know.

Best regards
Tobias

Tobias, - when I first test rode the Scrambler I felt it had a tendency to understeer when going round corners and roundabouts, and what I mean by that is that I found I was having to put more effort into turning it into corners than I expected. And I am not unused to similar wheel sizes and tyres since I am used to a R1150GSA on TKC80s.

Whether it is because I have got used to the bike, or the tyres have worn a little so the profile is not so extreme, or it is down to raising the handlebars but after 1,000 miles I don't notice an understeering characteristic and feel the Karoos have been fine in all sorts of weather.

Hope that helps

Thanx. Now I know.
I think it all depends..... This is one of the bikes I have had that hold it's lines best. I think I have found the limit of the rear suspension.... two person and luggage is to much 😂. So now I have to decide wich to buy. Been looking at Touratech high level suspension, expensive.... typ of....

Yes, I did 750 miles on the bike this weekend along all sorts of roads from motorways to stony single tracks - road holding was impeccable all the time (and easily kept ahead of a Triumph Explorer and a GS )

Limitations to me are the seat and the rear shock; became pretty sore after about 300 miles in a day. Considering fitting Hyperpro shock, or maybe just change the spring as this worked well on my GS. For the seat shall remember to put the air hawk on in future!

Same here. Did 1200 km this weekend. The seat and rear shock need som attention. Have you been looking at the Hyperpro?

Yes; on my GS just changing the springs worked well (could do the front myself but the rear was more complicated because of the remote reservoir I think and had to get suspension specialist to change it). Can't decide if that would be enough on the Scrambler - the rear shock does not seem to be the same quality as the old GS one
