After riding my Phantom 150 for 11 years, I decided to fit a nice pair of rear shocks on the bike. The originals were worn out, so I made a trip to LAB and got myself a pair of MIKUKU shock absorbers. Details below...
Made in: Thailand, though I suspect Malaysia
Cost: 7/10 ($70)
The shock absorbers look like the Super 4 SHOWA items. They are light and decently made, though the finish could be improved. You can adjust the preload (spring tension) and ride height (length) of the shocks, though the adjustment is very difficult to do if you don't have 3 hands!
The general quality of the shocks were disappointing; for $70 I would have expected something like the stock suspension, but hey, you get what you pay for. FYI, a pair of RXZ stock shocks will happily fit on the Phantom and they are cheaper at $65 (and also better made).
Performance of the suspension is decent; the rear is pretty stiff now and the bike does not wobble in corners. They look nice. Other than that, there's nothing else to shout about.
Before fitting the shocks, be sure to set the spring tension and the shock length EQUALLY for both units. This will ensure proper suspension performance.
The shocks are easy to fit. Procedure as follows:
1) Loosen bolts on the original shocks. Do not remove bolts yet.
2) Place a jack under the bike. Start jacking it up.
3) As you are jacking up the bike, remove the bottom bolt of the left hand suspension unit. There will be a point where the weight of the bike is taken up by the jack and the suspension becomes unloaded. That's when you pull out the bottom bolts.
4) Remove bottom bolt and top bolt completely.
5) Remove old suspension unit.
6) Install new unit on left hand side first. Grease the mounting points on the frame, as well as the mounting bolts. The reason for doing the LHS unit first is because the RHS unit is hard to install. The exhaust pipe blocks the bottom bolt on the RHS shock.
7) Install and tighten top mounting bolt. Install and tighten bottom mounting bolt. It may take some work for you to line up the mounting holes for the new shock.
8) Remove the RHS suspension unit.
9) Install the new RHS suspension unit, but do not attach the shock to the top mounting post. Instead, fasten the BOTTOM MOUNTING BOLT FIRST! If necessary, jack up the bike some more so that the bottom mounting bolt can be installed easily.
10) Finger tighten the RHS mounting bolt.
11) Lower the jack till the top shock mount lines up with the suspension unit. Slide the shock onto the top mounting post.
12) Tighten the lower mounting bolt. Tighten the upper mounting bolt.
That's it! You're all done.
Substandard pair of shocks; look good, average performance. Hard to adjust spring preload. Mounting holes were not the correct size; I had to modify them. Difficult to set the ride height to the same value for both shocks.
Buy the original shocks, or YSS or RXZ shocks. For looks, though, the Mikuku shocks are very good.
Hope you guys find this useful.
