Lowside question, front end feel?

So this past weekend I ran chuckwalla ccw and at t-14 I kept getting some weird feedback from my bike. Instead of being able to relax after turn in and let the bike cruise it's course I had to fight the bars to make the turn. The front end felt twitchy, as if it were sliding out a bit, and I would have to physically turn the bars to keep on line. Since I haven't been down yet I can only assume this was a sign that I was about to lowside. Any ideas as to what could be the issue. The rest of the track was fine and I had zero issues.
Basically I'm wondering if the description fits the feel of a bike about to let go? I would like to know in case it does let go I can relax and go with it instead of getting tense and fighting it.

Re: Lowside question, front end feel?

Tire pressure? Suspension setup?

Re: Lowside question, front end feel?

Q2's 30/29. I'm still on factory settings suspension wise. I plan on getting the suspension dialed in over the winter break but if it were the suspension I would think I would have problems with the rest of the track as well.

Maybe you are just really good on that turn and feel it there. I'll let others chime in. I have little faith in those tires. A few people I ride with complained of a similar sensation and in fact did lowside shortly afterwards in that spot.

So it could just be the front end getting ready to let go, but I can't be sure or make an accurate assumption. It's safe to say that not having the suspension setup ever isn't helping any.

Having to continuously provide input to the bars to hold a line is a sign of shitty suspension setup.

get your suspension setup and tires made for the track. Being prepared makes a huge difference at the track and it can keep you riding all day! the stock suspension setup isn't bad but its not intended for track use and is a bit soft and jumpy. After my first setup it was a noticeable difference in handling and feel.

Re: Lowside question, front end feel?

Yeah I need to get the suspension setup but the guy I want to go to basically works out of his personal garage and as such I need to get stands before we can get started. Strange to hear this input about the Q2's as pretty much every review I have read has been positive. They held really well at Willow Springs. Chuck is strange though, instead of beading up rubber on the tires it seemed like I was cleaning my tires up. They almost look like there brand new as the tearing and bald up rubber from my last track day was cleaned off.

That's a GREAT sign!! It means you're smooth getting on the throttle, and your suspension is probably not all that far off in regards to rebound settings

I rode em a couple times and didn't take to them well. I am partial to a softer carcass tire in general.

The surface at Chuck is only 2 years old, and much different compared to the way old pavement at Willow. That may be a factor in the tires cleaning up. I remember having similar wear the one time I was out there.

I rode Chuck clock-wise, so I don't know what T-14 is CCW, but it may be something as simple as the line your taking. I kept struggling with turn 5 at Big Willow. I kept randomly missing apexes and felt like I was fighting the bike to get it turned. After talking to a control rider I realized I was trying to turn in where the track was off-camber, and hence it took waaay more effort than expected to get the bike turned.

Re: Lowside question, front end feel?

Some great feedback. I think the OP has done a pretty good job of narrowing down the situation to help find a resolution. And like has already been mentioned, tire pressure and suspension can have A LOT to do with weird sensations - even isolated ones due to the nature of a particular turn.
Also as Fallis mentioned, it could simply be your approach considering the incident seems isolated to that corner.

I'm a huge fan of the Q2 and have had great luck with it. I had similar front end issues on Pures (the tires weren't a factor, just clarifying) on a turn that crests a hill at the apex - I was pushing a little wide. I adjusted my front ride height a few mm and it made all the difference in the world. My front end was sitting too high in relation to my rear - causing the front to essentially just "lay over" which made it push.

Good luck OP
