Funn RSX direct-mount stem in orange fitted to a Sur-Ron, clamping the stock 31.8mm handlebar

Sur Ron & Talaria Handlebars

Sur Ron and Talaria riders have been fitting Funn MTB handlebars for years. Downhill-rated alloy bars are built for bigger hits than most e-moto stock parts, they come in far more widths and rises than the original equipment, and because Sur Ron and Talaria use the same 31.8mm clamp standard as mountain bikes, the right bar bolts straight on. This page collects the Funn components that fit.

Will it fit? The 31.8mm rule

Both bikes ship with a 31.8mm handlebar clamp, so any 31.8mm Funn bar drops into the stock clamp with no adapters — a straight bolt-on swap. The one trap: some Funn bars also come in a 35mm clamp version, and the stock clamp will not hold those. If you order 35mm, plan to swap the stem or bar clamp to 35mm at the same time. Unless you are rebuilding the whole cockpit, stick with 31.8mm.

The parts that fit

The Upturn high riser is the bar most Sur Ron builds are after. It reaches up to 75mm of rise, which is exactly what a stand-up e-moto riding position wants: a taller, more moto-style front end without stacking spacers or fitting bar raisers.

The Kingpin suits riders who want a lower, more aggressive cockpit instead. It comes in 785mm and 810mm widths with 7mm, 15mm or 30mm of rise and six colours, with cut marks etched on the ends so you can trim it to size — order it in 31.8mm to keep the stock clamp (see above).

Running a dual-crown fork? The RSX direct-mount stem is a proven Sur Ron upgrade — for a Sur Ron fit, choose the 31.8mm bar bore with 30mm rise, the combination shown fitted to a Sur Ron in the product photos. Dual clamp rings hold the bar; the stock Sur-Ron bar stays compatible. Talaria riders should check the top clamp's bolt pattern against the RSX specifications before ordering.

What about grips and pedals?

Straight answer: they do not fit, so save your money. The throttle side of an e-moto runs a throttle tube rather than a bare 22.2mm bar, which rules out MTB grips — and with footpegs instead of cranks, pedals have nowhere to go. Bars and stems are where the upgrade is.

Fitting notes

Torque bar and stem bolts to the printed spec and tighten in a cross pattern. If you trim the bar, move your controls inboard first and cut equally from both ends. And after the first proper ride, re-check the bolts — e-moto vibration finds anything left loose.
