Why would it need a kickstart?
There's a few things I like about a kick starter vs. electric only.
1) If the battery has gone south, I can start the bike with the kickstarter, even my EFI-equipped RE C5 started using the kicker, with one cell dead.
2) Lots less to go wrong. 9 of 10 things that go wrong with starters are electrical issues.
3) Pretty hard to damage your engine kicking it over, if it hydro-locks. This shouldn't be an issue, but it is, because modern moto designers prioritize safety over reliability. This has led to components like a vacuum actuated petcock that will leak the tank's contents through a ruptured petcock diaphram, directly into the intake manifold. The first warning some of my Honda brothers got, after pushing the start button, was bang!, but by then it was too late. The automatic petcocks and electric starters make us lazy, we neglect the manual petcock, and BANG!.
4) Pushing the bike out of the gangway, and kicking it to life are the only exercise I get some days. The kicking and the subsequent roaring to life are very satisfying, much more so than the pushing, or pushing the button.
I don't mention the weight savings, because I'm not the kind of guy who removes his electric starter. I'm the kind of guy who ignores his electric starter.
I'd prefer to buy a Yamaha SR400 or early model SR500 with the wire wheels, or a Kawa W650. These are bikes that will gain in value over the years that I ride them, no matter how much I kick them.
If I was you, I'd hold onto that RE a few years longer, and put it on the market in the spring of a year a few in the future. You'll likely be able to put an extra $1000 or two in your pocket. Prices on RE singles have already climbed noticeably, in my opinion, at least here in the USA.
