Very Dinamik 6-speed Kapchai

POSTED BY Philip Chong ON 16 October 2014

Modenas Dinamik

Engine: 120cc. Check. Transmission: six-speed. Check. Gearbox: Manual. Check. This sort of summarises the basic features of the Modenas Dinamik 120 moped (or kapchai). And no, it is not a four-stroke machine but a two-stroke.

Together with Hong Leong Yamaha’s 125ZR kapchai, the Dinamik 120 remain the last of the super lightweight and nimble two-stroke mopeds that are still being assembled for the local market.

Like its main rival, the Modenas Dinamik 120 comes with a six-speed manual gearbox. It has 5cc less in engine capacity but made up for it with a better power-to-weight ratio. It has a dry weight of only 98 kg vs. 101 for the 125ZR.

In terms of specifications, the Dinamik 120 looks impressive but how does it perform on the road? Before we get to that, there are a few things to remember. One of them is – there’s no electric start button. You have to rely on the traditional kick-start lever to fire up the engine.

This is a very 20th-Century style of riding a kapchai in this age of the Internet and multiple electronic gizmos. To add further bewilderment, the Dinamik 120 comes equipped with a power kill-switch button similar to those in bigger bikes, surprising since Modenas decided to exclude an electric starter button for the bike.

The last of the old era feature on the Modenas Dinamik 120 is that the headlight does not come on automatically once the engine is started – we have to switch it on manually via the ON/OFF switch located below the engine kill-switch. The ON/OFF switch is a three-step design – first is OFF; second turns on the internal lights of the speedometer and the third lights up the headlight.

With the surprises out of the way, we had our first ride with the Modenas Dinamik 120. Acceleration from stop-go, the first two gears were fast enough to bring the bike further forward than most kapchais and cars while third and fourth leveraged on that to make it go even further. However, fifth and sixth are probably “cosmetic”, as the former doesn’t really do much and the latter is meant for top speed riding.

And what a top speed it is capable of. The Dinamik was clocked doing an actual 140km/h when we brought it up to speed on a private test track. Occasionally when it is used on public roads, it could keep up with most highway traffic with ease as it readily surges above 110km/h easily, compared to most kapchais which often struggle to reach 110km/h at full throttle!

Both the first and second gears are short ratio type; they are great to make the Dinamik go from an idle position but when it comes to negotiate your way out of congested city traffic, the third/fourth gears are the best option as the short ratio tendency of the low gears made the Dinamik hesitate if a quick getaway is what the rider wanted.

While it is light when we rode the Dinamik 120 at its top speed, it was quite stable with no vibration being felt at the handlebars nor was it in any risk of being swept off by strong winds at that kind of speed. Where it did bother us though was the amount of plastic buzzing coming from the plastic panels on the bike as these parts did vibrate.

Braking power is adequate with the Dinamik 120’s single front and rear disc brakes. When riding on the dry, both brakes slow the bike down with standard braking power. For front disc braking alone, we need to brake harder for it to slow the bike. Extra care must be taken when riding in the wet as the front brake pad lacks the precision needed to slow the Dinamik down. Applying both brakes hard in the wet tend to force the front tyre to lessen its grip on the wet tarmac.

We recommend switching to more reliable third-party Japan-made brake pads for the front disc to avoid the tendency of the front to fold itself under the weather.

With the acceleration, top speed and braking covered, what’s left is the average fuel consumption of the Dinamik 120. Honestly speaking, we are not sure if the fuel consumption of the Dinamik is rated as good, excellent or poor for its class.

Due to its relatively small 4.6-litre tank as compared to 5.5 or more from the competitions, we rode the Dinamik 120 to the last drop (literally) after 119.8km! That’s a combination of moderate, standard and top speed riding. Its consumption averages out to be approximately 25km per litre – which is quite good but a bit high when compared to its four-stroke rivals.

But its 4.6L capacity makes it quite a guzzler for fuel as the 120km average won’t be enough to last longer travelling distance without stopping for fuel top-up – it will not be adequate to reach Ipoh but could get the rider to Bidor or Tapah. Or Seremban or Tampin down south but not enough to reach Melaka city.
