While Royal Enfield has taken great strides forward to producing more reliable and higher quality bikes, the Thunderbird 350X is from a time when they were still trying to shake off some older era shenanigans. The bike’s simplicity is praised by some owners, who say it is easy to work on and parts are easy to get. Some have frequent electrical system, oil leak, and general reliability issues. The older RE models are getting older, so finding mechanics who are familiar with them is getting harder. And of course, parts availability – RE has a great history of supporting older models, but how long will that last? For anyone looking to buy a used Thunderbird 350X, is the maintenance part a big deal? Is the other value of the bike outweighing those potential reliability issues or is it better to go with a more recent bike and try to be more reliable?
