Kyosho ST-RR sets the new standard in truck racing!

The Kyosho ST-R established higher standards of quality and technology when it was introduced in early 2006, and now the new ST-RR competition truggy raises the bar even higher! The ST-RR is the culmination of a year and half of racing and rigorous R&D and the result is the most refined racing truck on the market. As the 2007 Silver State Champion, the ST-RR is poised to take it to the competition on a whole new level.

Features

• Long Chassis - The ST-RR chassis is 25mm longer than the ST-R. The chassis is the best performer chosen from four different prototype chassis tested. Instead of just guessing and producing a random long chassis, the designers and team drivers exhaustively tested different configurations of varying lengths and weight distribution to establish which provides the best performance. The front-weighted chassis that was chosen features extra length for rock-solid stability in the bumps, while concentrating weight as far forward as possible to give the ST-RR exceptional steering response. It's the best of both worlds; ultra crisp steering response and unrivaled stability.

• Big Bore Shocks - Bump handling is greatly improved with the addition of the new big bore shocks that are included with the ST-RR. The big 16mm pistons and shock bodies are 23-percent large that the shocks on the previous ST-R for great stability even through dramatic temperature changes and long main events. These shocks provide unmatched stability over jumps and through the bumps to give this machine an unbeatable edge in the heat of racing.
New accordion-style shock boots keep the big 3.5mm shock shafts clean.

• Chrome Moly Ring & Pinion Gears - The internal ring and pinion gears of the drivetrain are now formed of the strongest material, which means the ring and pinion gears will be better able to withstand the punishment of long races and the biggest, most powerful engines.

• Lightweight Universal Driveshafts - The new driveshafts feature a lightweight design and are made from ultra-durable chrome moly steel - the strongest and most durable material ever used. Installed at the front, center and rear of the drivetrain, all of the driveshafts feature a distinctive black finish.

• Low Profile, High Down-force Body - Looks are almost as important as performance to some racers, and the new ST-RR includes a modern, low-profile extended body to fit the long chassis of the truck.

• Extended Wing Mount - A new rear wing mount raises the rear wing 18mm and moves it 8mm to the rear, creating more down force for better jumping performance and improved high-speed handling and traction.

• Wide Offset Wheel Hubs - Previously optional wide offset hubs are now standard equipment for the ST-RR. They increase the width of the truck 18mm for more stability through uneven bumps and high-speed corners, which gives you the confidence to keep the throttle pinned through the rough sections for even faster lap times. Standard and medium offset hubs are still available for extra tuning options.

• High-Grade (HG) Air Filter - Introduced in the 777 WC Edition buggy, the HG air filter features a new high-density, high-flow foam that is more resistant to various types of filter oil. The high-density structure of the foam means this filter captures more dirt particles to keep your racing engine running stronger for longer. The high flow rate means that the engine can still breathe exceptionally well and maintain maximum power even through a grueling 1-hour main event. The faceted texture of the outer filter provides more surface area, which means it breathes better for longer than a standard round filter.

• Legendary Kyosho Quality - In addition to all the exciting new features, the ST-RR also features the unique manufacturing methods and premium quality materials that make Kyosho vehicles legendary for their quality, precision and durability. Most of the details are not obvious because some plastic parts look just like other plastic parts, but only the experience of seven 1/8 off-road World Championships (more than all other manufacturers COMBINED) provides the unique knowledge of exactly what materials and designs work best. Whether it's precision grinding for exact parts fit, high-grade race-tested composites, high-tech aluminum and steel alloys, space age coatings or premium-quality bearings, there are plenty of reasons why educated and experienced racers prefer Kyosho.

So let me see...

RR probably stand for Race Ready, and I'm going to go out on a limb, following their naming conventions (since they like to go in 3's- 777, KIII), and say they're going to come out with a ST-RRR, which I am assuming to be a Race Ready Racer? LOL

How much can you improve an already AWESOME product?

I like how they claim chromoly steel as the strongest material ever used. :cough: titanium :cough:

chromoly (4130) is very strong and it is used in many high performance applications and depending on the grade of titanium could be stronger. 6AL-4V titanium is stronger but commercial grade titanium is not.

[thedarkness]

Anyone looking for a BCE chassied STR?
Thats hot stuff right there.

Also chromoly is HARD Ti is SOFT, like comparing tungston to aluminum

[bspate]

Hhmm.........no mention of the new steering knuckles??

I would think they have to be included with this since they come with the new extended chassis conversion kit.

- bspate -

[StevePond]

The milled knuckles are not included with the kit. I realize that some racers would prefer to have machined knuckles even at a higher price, but the decision is to leave that choice to the customer. My personal preference would be to include them, but at least now the milled knuckles are available to those that want them.

[JatoThai]

nice lookin truck

[masterchief06]

You know Steve, along with the machines knuckles, would it hurt a race roller manufacturer to include threaded aluminum shocks too? Maybe this particular truck is not the race version (judging by the lack of cf and abundance of aluminum).

Just an observation

[thedarkness]

Threaded shocks are not ideal for 1/8th IMO

[masterchief06]

Really? What makes them less advantageous than pre-load style shocks?

Mike

[thedarkness]

I prefer clip on preload spaces because with threaded bodies they can get the threads clogged with dirt. Its also much easier to get the preload exact side to side with clips, threaded collars can back off, and its a whole lot quicker to pop a new clip on than turn a collar.

[masterchief06]

Cool. I never looked a it that way.

Oh this is very much the race version. I understand that most people are led to believe that the presence of carbon fiber and lots of aluminum equal performance, but it couldn't be farther from the truth. Maybe it's true in touring cars but none of the really competitive 1:8 buggies and truggies are laden with too much aluminum, and carbon fiber has no place on a buggy unless it's a low-stress area like a servo tray or steering brace. Don't be overly impressed by the cars with all the shiny stuff, they're only "fast" on the shelf.

[dgrobe2112]

also.. if you had threaded, you may have 4.4mm of preload on one side.. and 4.0mm of preload on the other.. only way to tell is with a caliper.. clips.. get you pretty close and even..

I must say i am a little disappointed in the fact they didnt include the CNC knuckles.. especially since they were included in the long chassis conversion..

[Hikari no Tenshi]

Hrm, I think i'll hold off on the purchase for the ST-RRR Evo WC Team Edition.

[thedarkness]

If its updating as it has been youve only only got a 6 year wait(update every 18 months)

[Hikari no Tenshi]

I'm ok with that, i'm very patient.

[taztal3]

i like the body wow . anybody know what is price ??

[RespirologyRC]

Dgrobe, I know you just bought the long chassis conversion, and now they are offering the full kit with big bores and updated unis...doesn't this just burn you? I know it definitely burns me.

I just spoke to a track owner who says that he doesn't like to carry kyosho stuff because they change their parts to quickly. Could this be an example of this? I think so. Look at losi and AE, they both have kits and make small updates from time to time but nothing major like this.

If i buy this ST-RR how long before they come out with the St-RRR WC Team Edition? 5 months??

I like the truck, like the way it handles, but don't like how frequently it changes. Change is good but to frequently is bad

[dgrobe2112]

Well, funny you say that.. because.. Kyosho is doing what their customers want.. when the STR came out.. over a year ago.. not 5 months.. everyone talked bout how good it is.. and it would be better with a longer chassis.. cnc'd knuckles, stuff like that.. so.. kyosho did it.. thats what people wanted.. then losi, and jammin, and mugen all released theirs with big bore shocks.. which kyosho has not done ever.. so.. the customers, team, and everyone else says.. kyosho needs big bore shocks.. which honestly.. STR still beatin the competition with stock shocks.. as you said in your other forum.. so they released the big bore shocks.... now.. with there being so much changing.. the new chassis, and the drive shafts, and all the new parts.. they updated the kit.. rather than selling the kit, then buying the long chassis conversion, then the big bore conversion.. then the new body.. its been over a year now since the release of the truck.. kyosho just wants their truck to be the latest and greatest..

I mean.. i see people doing upgrades all the time.. i have not upgraded my truck from stock at all.. i see people with KMW shocks, and long chassis on every other companys vehicles too.. not just kyosho.. big shock towers.. aluminum chassis braces.. all kinds of stuff.. kyosho is just offering it in a kit..

sure.. it would be nice to have this stuff all in one package.. but i race all the time.. and i want the products as soon as they come out.. which is why some people go to different manufacturers for these parts.. Racers Edge shock towers, or knuckles, or fioroni, chassis on the buggys, or chassis braces.. or toe blocks.. or lunsford turn buckles.. everyone does it.. Mugen aftermarket pillow balls, made out of different material, king headz aluminum chassis braces, or radio tray, stuff lke that.. fioroni shocks..

Kyosho is doing what the customer wants.. and putting these parts in the kit.. just the same as the others. Mugen MBX5, then a prospec, then an R, Xray XB8, then plenty of upgrades to that one.. all running changes.. now they got a 1 or 2 new version on theirs too..

Its all about getting the latest, and greatest technology into the cars.. so.. rather than buying a whole new kit, they offered the upgrades.. for the kit..

I can see how it burns some.. and i understand.. but you gotta know that no company is gonna sit idly by, and let the competition pass them.. if there is new stuff out there.. that will make performance better.. i am all for it.. i am all for a company who listens to their customers, and gives them what they want.. not saying kyosho is the only one..

In order for kyosho to sell the STR now.. they have to offer everythin in it.. and for the loyal Kyosho owners out there.. they are offering the parts as needed to get my current STR, into the ST-RR. rather than selling my current STR, for little to nothing.. and buying a new one.. just upgrading mine with the current released parts..

Losi, and AE, just released theirs.. just now.. so.. would you be upset if ST-R was just release also.. with these hopups.. these parts.. Kyosho was first on the market with the truggy.. before STR, everyone was running long chassis buggies.. with short arms.. and its been dominating the comp ever since.. sure.. those that followed.. offered different things.. big bore shocks.. stuff like that.. Losi, and AE are newest.. and have the newest stuff.. the 8T aint even that old.. what.. a couple months.. the STR is bout 2 years in design..

one major change to the truck..makin it an ST-RR, offering all the best that kyosho has to offer for this truck.. in bout 2 years..

I aint tryin to sound mad or nothing. im not.. just seems kyosho gets knocked cuz they releasing new stuff.. and a new kit.. how old is the MBX5, or the XB8, they keep the same name.. and add stuff to the name.. Prospec, MBX5-R, XB8TQ, XB8EC, ST-R, ST-RR SP1, SP2, SP2WC (which is basically a SP2, with some extra bits.. no major changes at all)

spendy truggy for one that doesn't come with hex screws

[dgrobe2112]

hex screws.. hahahah.. thats so funny.. but oh well.. the phillips dont strip as much as the hex screws i used to run.. one hudy #2 screw driver.. is the best tool i got..

[RespirologyRC]

dgrobe; good points...nah--> Very Good Points
I just want the big bore shocks.

Can one of the Kyosho reps confirm if there will be a shock up grade package or will we have to purchase the shocks seperately and the uni's seperately?
thanks
