TBparts now has an updated version of our popular plus 1.5″ extended aluminum swingarm kit for the Z50 K3-78 and all Z50R models. The previous version was a great performing swingarm that we sold for the last 10 years. We decided it was time for an update and this new one is exceptional!
Key Features:
- Uses solid billet aluminum sections for increased strength
- The billet center section is no longer welded on. Its notched into the billet side sections and then bolted on for increased strength (was previously a hollow section and welded on)
- The shock mounts have been redesigned for increased strength
- The chain slider is easily removed and replaced with two screws (was previously riveted on)
Specifications:
- Overall length - 13 5/8 inches or 346mm
- Overall width at axle - 8 3/8 inches or 212mm
- Overall width at pivot - 6 1/2 inches or 165mm
- Pivot to front of axle block opening - Approximately 10 5/8 inches or 270mm
Recommended:
- TBW1145 - 280mm shock set in black
- TBW1146 - 280mm shock set in chrome
- TRC-5319 - 280mm performance shock set in gold/black
- TBW0916-Z50 - 280mm vintage shock set
Its a very high quality aluminum swingarm that increases strength and improves handling on the Z50. This new version is better suited for pavement racing or backyard pitbike fun and you don’t need to switch to a longer front suspension (your OEM front end is fine with this swingarm). Unlike many other similar looking Z50 swing arms on the market this one uses solid billet aluminum sections, the pivots use bearings instead of the stock type rubber bushings, and it was purposely designed for adult abuse. Please compare closely to the competitors. These are definitely not the cheaper poor quality hollow aluminum Chinese $75.99 ebay specials you see around that will snap after a couple jumps.
