I have had several motorcyle parts from India off Ebay without any problems or additional fees / taxes, the latest being a rear carrier for my (Indian manufactured) Royal Enfield Classic 500 delivered last Saturday. 8 days from placing order to delivery, with the tracking information being updated along the way. Delivered cost was £33.59 for this item.
AFAIK Ebay are now responsible for collecting taxes on imports, so a UK Ebay listing should be all inclusive.
But that RT doesn’t seem much cheaper than buying from a known UK supplier – Chronos have something that appears very similar for under £75 delivered within the UK that also includes a few basic clamping parts. Easier to return within the UK if it isn’t up to scratch.
