Couldn't load pickup availability
The genuine Royal Enfield 888146 – Centre Stand & Spindle Kit is the OE kit supplied for bikes that use the Thunderbird/Classic UCE frame layout. Multiple trusted dealer sources list it exactly as “CENTER STAND & SPINDLE KIT – TB 350 & 500” and also show the same part number against Classic 350 (UCE) and Classic 500 EFI, confirming that Royal Enfield used this kit across these UCE models.
This kit gives you the complete main stand setup – the stand + spindle to mount it – so you can restore parking stability, chain-cleaning convenience, and workshop-style support. Because it’s OEM, the stand height, stop position, bushes and spindle length are all correct for the frame, so the bike lifts cleanly without leaning too far to either side. Perfect when your original stand is bent, over-rusted, or missing the spindle. We are listing only the confirmed models below to keep returns low.

FAQs
Q1. What exactly is in 888146?
It’s the centre/main stand with its spindle for the TB/Classic UCE frame, as sold by multiple RE parts dealers. Springs/fasteners may be ordered separately depending on your fiche.
Q2. Will it fit my Classic 350 UCE?
Yes – several dealer sites list NTB 350 | NTB 500 | CLASSIC 350 | CLASSIC 500 EFI for this part number. We’ve reflected only those in the table.
Q3. Does it fit Thunderbird X?
Not clearly called out in the sources we checked; treat as not confirmed and verify by VIN.
Q4. Why is spindle included?
Many failures are because the stand AND its pivot wear together. Supplying both ensures the stand sits true and lifts smoothly.
Q5. Do I need to paint it?
It comes finished for use; just grease the spindle during install.
