TBparts Gold TiN-coated fork assembly set with HD springs paired with a 290mm, 340lb DNM rear shock. This suspension combo delivers a serious performance boost for your 2010+ KLX110 or KLX110L and is priced together for the best value possible.

TB Fork Assembly Set, HD Springs & Gold TiN-Coated Uppers – KLX110 & KLX110L

Now available with gold Titanium Nitride (TiN)–coated uppers! These forks feature adult-weighted HD springs, making them far better suited for adult MX riders compared to the very soft OEM springs designed for kids trail riding.

These forks pair perfectly with our 250–350lb+ DNM rear shocks. The damping rods are ported to match the heavier springs, providing improved damping and rebound control to keep the front end stable instead of feeling like a bouncy “pogo stick.” The damping rods are also lengthened, giving the forks additional travel.

For added durability, we integrated an OEM-style internal bushing/guide inside the fork bottom, increasing strength over the original Kawasaki KLX110L forks. Altogether, this fork set delivers unbeatable out-of-the-box performance and value.

Why Gold Titanium Nitride (TiN) Coated Uppers?

Titanium nitride coating offers real performance benefits beyond appearance. TiN is approximately twice as hard as traditional chrome on the Vickers hardness scale, greatly improving wear and scratch resistance while extending fork life.

The coating also provides increased lubricity, allowing the uppers to glide more smoothly through the seals and bushings for consistent, smooth suspension action.

Advantages of Titanium Nitride Coating

Increased hardness: 2400–2600 Hv
(Chrome: ~940–1210 Hv)
Increased lubricity / low coefficient of friction
Wear and temperature resistant
Corrosion resistant
High-quality, long-lasting finish
Extends life, improves performance, and enhances appearance
Applied using Physical Vapor Deposition (PVD) process

Fork emulators for OEM KLX110 forks do not fit TB forks
(They also reduce travel, require tuning, and add unnecessary cost)

Disclaimer

These forks have undergone extensive racing and jumping testing. They are designed similarly to OEM hydraulic telescopic forks with the upgrades listed above. Like OEM forks, they can still bend if over-jumped or flat-landed.

For best performance and long service life:

Avoid flat landing jumps
Do not jump ramps larger than what factory-style forks are designed to withstand

Considering inverted fork conversions cost three times as much, this bolt-on suspension kit offers unbeatable valuefor the KLX110 & KLX110L.
