KBS Tour Lite Shaft Chart: 95g R, 100g S, 105g X Weights and Flex

The quick answer: KBS Tour Lite comes in three specs and weight tracks flex — Regular is 95g, Stiff is 100g and X-Stiff is 105g. KBS describes it as roughly 20% lighter than the KBS Tour, and the design goal is higher trajectory, a little more spin and tighter dispersion in a lightweight steel package. Torque runs 1.9° to 2.1°, high flight across the range. There is also a Regular/Stiff combined flex in the parallel-tip version. The full chart is below.

Tour Lite exists to solve a problem that most steel iron shafts create. A standard steel shaft is 110 to 130 grams, and for a large number of golfers that is simply more weight than their swing can carry cleanly for eighteen holes — but the alternative has usually meant leaving steel entirely for graphite, which changes feel, cost and resale all at once. Tour Lite is the middle option: real steel, real KBS feel, roughly twenty grams lighter than the shaft it is based on.

This chart gives the three specs, the swing speeds each one fits, the torque figures, and an honest comparison against the KBS Tour it is derived from and the lightweight competition. Weights below are the manufacturer's own and torque comes from the same shaft database that powers our club grader.

KBS Tour Lite Shaft Chart: Weight and Torque by Flex

Weight climbing with flex is the KBS convention, used across the brand's steel range — the same system that makes a KBS Tour 110g in Regular, 120g in Stiff and 130g in X-Stiff. You do not choose weight and flex separately in this line; picking the flex picks the weight.

The R/S combined flex deserves a note because it confuses people. It is a parallel-tip shaft designed to be trimmed to play in the gap between Regular and Stiff, and how much you tip and butt trim it shifts where it lands. That flexibility is why it exists, and also why two builders can hand you an R/S that plays differently. KBS is explicit that trimming changes how the shaft plays.

What Swing Speed Each Tour Lite Flex Fits

These are driver swing speeds used as the reference point, which is how essentially every published flex chart works. Your iron speed runs roughly 10–15 mph slower for the same swing, so a 7-iron in the mid-70s usually corresponds to a driver around 90.

Because Tour Lite is a lightweight shaft, there is a second question alongside the flex: whether the weight is right for you at all. Both are in the table:

These bands follow our brand-neutral swing speed shaft flex chart. The 90–99 mph stretch is exactly the territory the R/S flex was built for, and it is also where tempo decides more than the speed number — a smooth, gradual transition stays Regular, a quick and aggressive one goes Stiff.

One caution specific to this shaft: do not treat Tour Lite as a softer flex. A Tour Lite Stiff is a stiff. If you are choosing it because full-weight steel feels like hard work, the right move is the same flex you already play in the lighter shaft, not a step down as well. Add your set in the app and the grader will score flex and weight progression separately, which is the distinction that matters here.

Tour Lite in Context

KBS Tour Lite vs KBS Tour

Tour Lite is derived from the KBS Tour — the 2008 shaft that built the brand — and KBS puts the weight saving at about 20 percent. In practice that is 95/100/105g against the Tour's 110/120/130g, so the gap widens as you go stiffer: fifteen grams at Regular, twenty at Stiff, twenty-five at X. Flight goes up and spin goes up slightly, which is the trade for the weight. If you play a KBS Tour and want the same feel in a lighter package, this is the direct sibling, and you should stay in the same flex letter.

Where Tour Lite sits in the lightweight steel market

At 95 to 105 grams it is genuinely light for steel without being extreme. For comparison from our own database, Project X IO ran 105 to 115 grams and Project X LZ runs 110 to 125, so Tour Lite undercuts IO by ten grams and LZ by fifteen to twenty at a comparable flex. Below Tour Lite you are into graphite iron shafts, which start around 45 to 70 grams and change the feel entirely. That makes Tour Lite close to the lightest steel worth considering before the material question becomes the real decision.

Taper tip versus parallel tip

Tour Lite comes in both a 0.355 inch taper tip and a 0.370 inch parallel tip. Taper arrives in per-iron lengths ready to install. Parallel is a single blank that gets tip and butt trimmed to length — KBS notes explicitly that trimming can change how the shaft plays, and that a 3 through PW parallel set is eight pieces. For most golfers the taper version is the simpler build; the parallel version exists for builders who want to tune the profile, and for the R/S flex which is parallel only.

Who should not buy Tour Lite

Two groups. If your problem is that you launch the ball too high or spin it too much, a high-launch lightweight shaft makes both worse, and the honest answer is a heavier, lower-launching profile like KBS C-Taper or Project X. And if you want a lighter set because you have lost speed with age, be careful not to change weight and flex in the same step — do the weight first, keep the flex, and see what the ball does before softening as well.

The Distance Claim, Read Honestly

KBS states that independent testing showed the Tour Lite series averaged 9 percent more distance than its leading competitors. That is the manufacturer's own claim and the test conditions are not published, so treat it the way you would any brand's number — as a signal of what the shaft is designed to do rather than as a result you should expect.

The mechanism behind it is real enough, though. A lighter shaft lets most players swing marginally faster, and a higher-launching profile converts that into carry for anyone who was flighting the ball too low. Both effects are largest for the golfer who was over-shafted to begin with, which is a big share of the people who end up trying Tour Lite. If you are already well fit in full-weight steel and launching properly, expect the weight saving to show up as less fatigue rather than as yards.

Frequently asked questions

How much does a KBS Tour Lite shaft weigh?

Weight tracks flex: Regular is 95 grams, Stiff is 100 grams and X-Stiff is 105 grams. The parallel-tip Regular/Stiff combined flex lands around 100 grams depending on how it is trimmed.

What is the difference between KBS Tour and KBS Tour Lite?

Tour Lite is the lightweight version of the KBS Tour, which KBS puts at about 20 percent lighter. In numbers that is 95, 100 and 105 grams against the Tour's 110, 120 and 130. Tour Lite also launches higher and spins slightly more. Stay in the same flex letter when moving between them.

What swing speed is KBS Tour Lite Stiff for?

Roughly 95 to 110 mph of driver speed, the same as any stiff flex. Tour Lite Regular suits about 75 to 95 mph and X-Stiff suits over 110 mph. Tour Lite is a weight choice, not a flex choice, so do not drop a flex letter just because you are moving to the lighter shaft.

Is KBS Tour Lite good for seniors?

It is one of the better steel options for a player who finds full-weight steel tiring, because it saves fifteen to twenty grams per club while keeping the feel and resale value of steel. The high launch profile also helps get the ball up. A senior golfer who needs to go lighter still would be looking at graphite iron shafts rather than any steel.

What does R/S mean on a KBS Tour Lite?

It is a combined Regular/Stiff flex, available only in the 0.370 inch parallel-tip version. The shaft is trimmed to play between the two standard flexes, and how it is tip and butt trimmed shifts where it lands, so the same R/S built by two different fitters can play differently.

Does KBS Tour Lite launch high?

Yes, high launch is the design intent across all three flexes, along with slightly more spin than the standard KBS Tour. That makes it a poor choice if your existing miss is a ball that flies too high or spins too much, and a good one if you are struggling to get enough height out of your irons.
