Kyosho MP9 TKI4 Review

The Kyosho MP9 TKI4 is marketed as a new generation or at least an improved iteration of the famous MP9 platform. It is also adapted for higher grip surfaces that are becoming more popular throughout the world, especially in Europe.

Some of the changes that Kyosho has made for the Kyosho MP9 TKI4 includes having drive shafts of the same length so you don’t have to carry 2 different pairs of spare parts. The new rear hubs now come with two mounting locations instead of one, thus allow more adjustability in the roll center.

The new rear wing design has also received a lot of attention and for good reason. When vacuum-formed wings were first introduced, it was found that while the reduced weight improved performance, the polycarbonate material lacked durability. The TKI4 wings feature a thinner construction that offers similar weight savings while maintaining durability to survive crashes.

Some of its other features include:

  • 1.5mm X 5 hole shock pistons
  • Larger receiver box opening
  • Improved shock boots
  • Stronger rear arms
  • Stronger hinge pins
  • Improved Ackerman steering knuckles
  • Longer, reinforced front a-arms
  • Uniform 93mm front & rear universals
  • Lighter wheels
  • Improved air filter design
  • Lighter, vented clutch bell
  • Longer cab body
  • Reduced hinge pin angle on front suspension

Durability

As compared to its predecessor, the MP9 TKI3, the Kyosho MP9 TKI4 is considerably more durable. The a-arms of the MP9 TKI3 broke frequently, whereas the a-arms of the new generation Kyosho MP9 TKI4 are 2mm longer and reinforced with a bunch of webbing inside to make the arms more durable.

Performance

Kyosho also changed the front end geometry with the front suspension mounts changed to raise the hinge pin by a couple of degrees, thus flattening the kick up to make the car a little more aggressive. This is a double-edged sword and it really depends on your driving style and your track condition.

If you are running the car on a loose and loamy track, you would want to consider adding more kick up to tame the car down. If you are on a higher grip track and want to go touring-style, then the flatter kick up is the way to go.

Kyosho has always been known for their tame cars right out of the box, however, Kyosho has made the Kyosho MP9 TKI4 more aggressive right out of the box. While the car does drive good, on a loose and loamy track, it can be a handful to drive with the box setup.

Of course, that being said, there are many things you can do to tame the car – using different diff oils, shock packages, add some kick up, and more.

Cornering

The longer front arms, longer front steering links, and improved Ackerman steering angle really improved the corner speed of the car.

Conclusion

Not surprisingly, the Kyosho MP9 TKI4 is another great kit from Kyosho. This car is not the cheapest to maintain as the parts are not inexpensive being that it is a Japanese platform.

Overall, another great kit by Kyosho and I had a great time building and racing the Kyosho MP9 TKI4.
