Comparing the KBS Tour 90 vs. 105
The KBS Tour 90 and Tour 105 are very similar. However, there are a handful of differences you should know about if you’re in the market for a new golf shaft. Let’s break down each of the important specs to keep in mind below.
| Spec | KBS Tour 90 | KBS Tour 105 |
| Weight | 95 g (3.35 oz) / 103 g (3.6 oz) for stiff | 105 g (3.7 oz) / 110 g (3.9 oz) for stiff |
| Length | 36.5 in to 40.5 in (92.7-102.9 cm) | 37.5 in to 41.5 in (95.2-105.4 cm) |
| Speed | 78 to 84 mph (125.5-135.2 kph) | 82 to 88 mph (132-141.6 kph) |
| Flexibility | Low to Mid Stiffness | Low to High Stiffness |
| Butt Diameter | .600 in (1.5 cm) | .600 in (1.5 cm) |
| Tip Diameter | .355 in (0.9 cm) | .355 in (0.9 cm) |
| Playstyle | Slower Swings | Semi-Aggressive Swings |
Golfer Troop also explains that the KBS Tour 90 is designed with a softer tip for added forgiveness and hangtime. However, the softer tip can reduce the sound quality compared to the KBS Tour 105. This means the 105 is slightly better at identifying poor swings and back contact with the golf ball.
Should You Get the KBS Tour 90 or KBS Tour 105?
You should get the KBS Tour 90 if you have a slow swing and you want to improve your precision. The 90 is also better for people with pain in their joints and muscles. On the other hand, The KBS Tour 105 allows for a slightly more aggressive playstyle and a faster swing.
Driving Range Heroes claims the KBS Tour 90 is one of the smoothest shafts, cutting through the air during the backswing and downswing. This makes your swing seemingly effortless, helping you focus on making contact with the golf ball.
However, the KBS Tour 105 reduces the vibrations going back through the shaft, keeping your hands nice and comfortable. These vibrations are common with lightweight shafts, but Driving Range Heroes reports the flexible center and stiff tip and butt protect your hands.
Whether you choose the 90 or the 105, you’ll have a lightweight shaft to improve your smoothness, swing, and overall performance.
Final Thoughts
While the KBS Tour 105 is faster than the 90, the 90 provides a slight precision edge. It’s also better for achy joints, though the weight difference is very minimal. The majority of the comfort difference lies with the KBS Tour 90’s easier backswing-to-downswing transition.
