OTK vs Tillet seats

1

Looking at a seat replacement and looking for some input.

From my research it appears that Tillett standard seats are a bit stiffer than OTK and the “t” series is slightly more flexible than standard but similar to OTK. Is that accurate?

Also, with a taller driver would going slightly stiffer on OTK frame aid in freeing up the kart?

Not going 9 or 9.5, going to stay with 11 if I use a Tillett. Way too hard to find the 9/9.5 in a size that fits my kid.

So with all that, would we expect to free the rear up any going from and OTK to a Tillett T11?

Not sure how tall your driver is. But I am 6ft. I was recommended to run the T11VG and I did the past season with lots of success

The OTK and T11 are very similar in my experience.

If you are looking to free up the kart, I would see if you can get a VG seat. That kind of became the baseline for lots of OTK guys in the past few years. If I recall you guys took chrome seat struts off last race and liked it. A stiffer seat will work sort of the same as adding seat struts; you’re stiffening up that area between the frame rails and the kart will physically feel stiffer and flex less.

To free the kart up as much as possible I’d recommend the T11VG. Like TJ said a lot of guys are running that on the OTK with a lot of success.

I ran the VG as standard since 2018 and I liked it. The last race I did was the Route 66 race at Dousman, and even on that fairly low grip track with me being not very tall, I found the VG with two chrome struts to be too stiff by the final. So even if you need to stiffen the seat up at some point, you can get it pretty stiff. Gives you a lot of range.

Thank you both.

Yes, he very much likes the rear free. We were on HH, full wide, no struts, flat front bar by the end of last race weekend.

I like the Greyhound RS3, equal to the T11VG

Looking to buy a Tillet T11 VG.
Does anyone know what size corresponds to an OTK size 3 seat, had not much luck contacting Tillet.
A bit wider on the ribs would be ok, but definetly not smaller.

Thanks!

Just compare seat charts. Find one that’s close to a size 3 bet wider in top dimension.

as I’m sure you know all of these seats have a slight variance even the same size seat from the same source. My brother and I both used to run size 3 OTK seats and have moved to Tillet. I think the ML is the most comparable to a size 3. That said, the Size 3 was tight on me and the ML was just as tight in different areas and started to cause some rib pain from really being compressed in the seat. I have since changed to Tillet size L instead and I’m much more comfortable in that seat, might be a touch lose but no rib pain since the switch. My brother tried the Tillet L and thought it was too lose and went back to the ML size. So if OTK is a good fit odds are you’ll like the ML. If the size 3 is tight on you you’ll better fit into a Tillet L
