Hello,

I recently got a Suzuki Vanvan 125 and I would like to install a rev counter. Does anyone have any experience with that on a Vanvan? Any recommendations in terms of rev counters generally?

Thanks,

There are a few threads on the Suzuki VanVan forum that talk about tacho fitting but none of them are particularly helpful because they don't mention the make and model of the tachos mentioned:

https://suzukivanvan.forumotion.com/forum

I suspect you'll have to register to be able to use the forums and the forums' search function.

But yes it can be done. The price of the best analogue tacho mentioned on the VanVan forum was £60 - it lights up and it apparently works accurately.

In some ways I wonder if a gear selection indicator might be as useful? By which I mean, if you were to go with a general common-sensical / mechanical sympathy approach, you could limit your speed in first to 10mph, 2nd gear from say 5 - 20mph, 3rd from 25 - 30mph, 4th from 35 - 40mph, and fifth from 40-55mph or whatever top speed is. I'm just reeling off these gear / speed pairings thinking that the bike has a single cylinder, 4 stroke 125cc engine. But some of it is dependent on what sprockets are fitted - but assuming standard gearing, I won't be too far wrong. The engine will be relatively happy in those gears at those speeds, I think. It won't be bogging due to travelling to slowly in too high a gear, and it won't be revving too highly because you're travelling too fast in too low a gear.

If you're a learner and you're coming to bikes having only driven cars, you might be prone to changing up too early. If the VanVan had a tacho with a red line on it it would probably be around 8k revs, and will rev to 6k without too much trouble. I'm not saying keep it at six thousand revs, if you're in first, second or third (although the engine will stand it). It'd be better to change up, imo. I just mean that car drivers can often ride the bike into bogging down and lugging because they assume the bike's engine doesn't want to rev too much passed e.g. 4k. But they do, and are best doing that - at least in so far as it's healthier than going too far in the other direction.
