I think Tilly is a great class for people who want to race on a even field. And dont want to race against I have more money than you have . Racing Classes .. And its a great beginner Class.. So yes Karting could use Tilly T4 Class in USA ..Another great alternative to other classes..
I understand YOUR take on it. However, the entries do not indicate the same reception by racers in the region. See copy/paste directly from event registration:
Race is still 2 weeks out and current overall entry counts look light. Regardless, there are only 2 entries for the T4 class right now. In theory its a nice idea to have something between the 9 HP LO206 and 22HP KA100 that isn’t nearly as expensive as KA100. But the consumer does not appear to agree and it shows in the entries.

Chuck, I agree with your point, but look at the T4—it’s barely been out and they’re already on a Generation 2 engine because of overheating issues. T4 track in Orlando has had 10 or so karts on track at the same time, but the Lo206 defiantly trumps that. I think there’s a big difference between people saying they support the platform and actually owning one. Every owner I’ve met is only running it because they have a contract with T4 or renting it. On the outside looking in makes me think they are not as readily available and there certainly isn’t a big used market, it seems easier and cheaper to get a new or used LO206 on a new or used chassis and go racing. I feel like T4 is just a glorified concession kart. If that ‘in-between’ category were actually necessary, people would just buy a World Formula (WF), which is only $200 more than an LO206. Bottom line T4 is a concession kart until proven otherwise.

Nothing unnecessary, that I can see. Hopefully no brake nonsense.
I not shilling, just chilling, and god willing, etc.
This stands out to me, in a very competitive market. Interesting engine. Race-focused kart made as light as possible while still being suitable for Pub sessions and the Noobs.

St. Pete race Dixon, Bourdais, and others were doing a benefit for kids in those this weekend.
Good write up, these look like they will be able to serve a large market. What does brake nonsense mean?
On rentals there are optional systems that seek to limit engine damage from double pedaling. As you can imagine, for those of us who like our TCS/ABS Off, for rotational reasons, these systems are no bueno.
Basically they kill power if they sense any brake pedal change.
Main offenders BizKarts who make otherwise lovely karts.

The catch is they are tilly-powered, so, in for a penny, in for a Euro…
In the good ol USA, the Honda GX270 is the dominant engine. It’s a very hard 
for Tilly to crack.
The Honda is an industrial engine so it’s cheap, easy, but parity stinks. The Tilly is a “race” engine so I imagine it’s lighter and more tightly manufactured.
That being said the engine seems awesome and perfect. But, I think you would need to understand the support you get if you buy a fleet.
@KartingIsLife is there a way to tag like we do in insta? Logic being, this sort of stuff can draw attention to KP when we discuss someone’s product.
@Bimodal_Rocket, don’t disagree your points. But you are talking concession karts vs owner kart racing. Just don’t see place for the Tilly in owner karting unless Briggs 
the bed. On concession karting, the Honda is gonna be tough to displace as well. I think electric will take more market from Honda than Tilly will.
@Vash_Stampede I like the idea of an in between offering, but I don’t think there is a place in the market for one. If there was, WF would have worked. Briggs had a huge market and WF failed. I don’t see Tilly succeeding in that niche if the incumbent failed. As for the T4 package, its like the Margay Ignite series and will likely only have a niche following like the Ignite.
True, this is something I didn’t even consider. If I was buying or leasing a fleet I would be very worried about the type of support I would receive state side.
By large market I was referring to the fact that I think both an enthusiast and casual driver would enjoy driving these. In terms of power it is slightly above a Honda, but not quote as unwieldy as a 2T rental.
So unbelievably true. When I was growing up driving the Hondas, there was as much as a 1-1.5 second difference between any given motor at my local indoor track.
In complete agreement. Was just saying Wowza! Re: their renal kart and I wish them the best.
Winner Winner Chicken Dinner! Or No Soup For You!
The e-market IS the market. Look at what is being developed.
Gas is the “racers” luxury now. HQ is getting gas fleet for “pro” drivers on top of their e-fleet. I approve.
Tags are supported at the topic/thread level. Not sure about post level though. Is that what you mean?
Entries look to be light this year. Late entry fees coming up, so I expect the fields to only grow a little. Even still, sitting at 4 entries for T4
Interesting disparity between the junior and senior numbers in KA/Briggs. While the senior classes are almost identical, the KA jr class has 12 more entries than the Briggs junior class.
I’ve always felt the move from sportsman to junior was not exciting for the driver, as the junior package is slower than sportsman an more technical tracks.
We started in Jr so didn’t know any different. Definitely heard plenty of frustration with Cadets being faster than Jr. There has been a similar trend for the 3 previous seasons we participated in TSRS. Seems like the Sr classes are pretty close to even but the Jr classes the 206 runs at just a tick over half of what KA does.
Last year there were 55 206 Sr and 66 KA Sr entries in the series with 24 206 Jr and 39 KA Jr. In 2024 there were 52 206 Sr and 59 KA Sr entries with 22 206 Jr and 42 KA Jr.
In 2023 there were 55 206 Sr and 55 KA Sr entries with 20 206 Jr and 38 KA Jr.
Dang I am going to miss not doing it this season…2023 in 206 was a fun year, placing 7th our first season. The jump to KA was a kick in the teeth though. 1st year off the pace and behind the learning curve. 2nd year full of DNFs that didn’t reflect pace gains he made. Then college and not enough $$ to juggle it all for this season.
Had a better turnout than I expected. Total of 9 T4 entries participated. Overall numbers for the Sr classes were down some, with 31 vs 37 for 206 Sr and 29 vs 38 for KA Sr at the same event last year. So I guess 9 was respectable for a first time out with a 20% softer Sr entry list overall.
As for the on track racing, they definitely looked like they drove different and looked to be harder to fire off the tires. The overall lap was 2 seconds faster in the mains for the Tilly at 01:00.700 versus a 01:02.712 for the 206 and was 3 seconds faster in qualy at 59.456 vs 01:02.085. For comparison the KA Sr was at 54.6 qualy and 55.5 mains. So not that much gap over 206 and not all that close to KA with current tire, with Evinco Blue would likely be different.
About the only negative I noted was that out of only 9 karts, at least 2 had engine gremlins. The 206 reliability is still pretty solid win for Briggs.
May come back and post more to this if anything eventful trends during the TSRS season…

Would you be able to elaborate on what the problems were? There is another thread on here or reddit where someone is discussing multiple engines on their grid suffering catastrophic failure after only 6-8 hours. 2 engines failing in a 9 kart grid doesn’t sound too good…

Ah, I found it, I was wrong about 6-8 hours. Looks like it’s worse in some cases.
Seems like reliability issues related to running in the heat potentially?
Do they still have a dyed, spec oil?
