Best retro helmet for less than £200

Q. I’m looking for an open-face helmet to wear on a Triumph Bonneville and I’ve about £200 to spend (although I’d rather spend less!). Cheap motorcycle helmets for sale. What are my options?

A. In case you missed our 2011 helmet supplement a few weeks ago, there are a number of cool-looking lids in your price range. How about taking a look at either of these? The Bell Jet R/T (from £175), Davida Jet (from £225), KBC Jet Vintage (just £100) or Premier Anniversary Vintage (£170) are all worth further investigation.
