Suzuki is developing a VVT (variable valve timing) system for a small engine.

VVT and variable valve lift (VVL) are not a new technologies as many manufacturers are already employing it in their products, but Suzuki’s system appears to be for a 250cc engine. This bodes well as there are either large capacity and small capacitiy motorcycles employing it but not the 250cc segment.

Suzuki’s system is basically similar to Yamaha’s VVA (Variable Valve Actuation) used on the NVX scooter, Y16ZR moped, and YZF-R15. It uses a camshaft with two cam lobe profiles, one for normal low end, low demand application, while locking on a higher lift and longer duration cam lobe at high speeds or big throttle openings.

As such, it is the best of both worlds: Good low and midrange RPM torque with high maximum power. Engineers have to pick one characteristic: low RPM torque, midrange torque, or high end horsepower without VVT and VVL. Using VVT also allows the engine to produce cleaner emissions as it cuts down on unburned fuel.

As aforementioned, Suzuki’s development centres around the parallel-twin 248cc engine. Patent applications show an engine with an unchanged bottom end, a cylinder head with a single camshaft driven by a centrally mounted chain. It is the same engine used on the GSX-250R and V-Strom 250.

The same engine, enlarged to 298cc is also in use by Suzuki’s partner Haojue in China. Haojue is the firm responsible for producing the V-Strom 250 and GSX-250R.

Suzuki current does not have any models in between GSX-R125 and 650cc models (V-Strom 650, SV650) in the United States due to emissions control, so a range of 250cc bikes with VVT will fix that.

QJMotor is one of several brands under the Qianjiang empire that keeps churning out model after model of bikes, some of which become Benelli, or at least share platforms. Case in point, the QJMotor SRT600 which is set to replace the SRT550.

The SRT550 was based on an important platform. As we mentioned earlier, its engine and chassis are the same as the Benelli TRK 502’s. The TRK 502 has since stopped production but is still available in Malaysia. This platform is also used by the MV Lucky Explorer 5.5, as the result of Qianjiang and MV Agusta’s coorperation.

But here’s something a bit confusing. Although the type-approval documents is for the new QJMotor SRT600, it  uses the same 554cc capacity. However, there is a large increase in power, kicking up from from 47 hp to 60 hp. Looking through the catalogue, we find that power level in the SRK550RR and RS sportbikes, meaning the “new” SRT600 engine is actually the higher-spec unit.

One welcomed relieve (if the bike becomes Benelli and is sold in Malaysia), is weight reduction. The document lists 220kg, against the exhuastive 234 kg of old.

The SRT600’s design is also another welcomed change, breaking away from the cheap GS beaked look. Instead, QJMotor redesigned the bike to a more familial bond with the V-Twin powered SVT650 adventure bike.

Other features apparent in the pictures are Brembo radial-mount front brake calipers. Tyre sizes are 110/80-19 for the front and 150/70-17 at the back.

Will this be the new Benelli middleweight to replace the overstayed TRK 502? Time will tell.

While we adults understand the importance of wearing a helmet when we ride motorcycles, a study conducted has found that the majority of children’s motorcycle and bicycle helmets in Malaysia fail safety standards.

The survey was jointly conducted by the Malaysian Medical Association (MMA) and Road Road Safety Marshal Club of Malaysia (RSMC).

Children’s motorcycle helmets

The two bodies had purchased 10 child helmets from retails outlets, with an additional 10 from online platforms. The helmets were then set to the Standards and Industrial Research Institute of Malaysia (SIRIM) for testing.

The test results were alarming. Of the former group, only 5 passed safety standards. The batch bought online fared even worse as 7 failed.

All helmets were tested against the newly-proposed and much overdue MS 1-2:2023 helmet standard. The Malaysian Institute of Road Safety Research (MIROS) and and SIRIM had proposed to implement the new standard.

Children’s bicycle helmets

As for child bicycle helmets, 11 were purchased from retail shops and another 10 from online stores. They were also sent to SIRIM for testing to the current MS 1763: 2004 bicycle cycle helmet standard .

6 from retail outlets failed while 7 from online stores failed.

MMA and RSMC noted that the retailers were generally aware of the standard requirements for child motorcycle helmets but not so for child bicycle helmets.

A worrying state of affairs

“Some retailers were unaware of the quality of the helmets they were selling. Some retailers verbally said that the helmets meet standards while there were no labels on the helmets.

“Some of the helmets sold had a QC label implying that they met the manufacturers’ standards,” said the statement.

It added that the majority of the bicycle helmets did not have a standards certification label while some had labels of foreign standards that were acceptable, such as USCPSC and EU standards.

“Some of the helmets were labelled ‘toy’. Some were flimsy,” it said.

MMA and RSMC urged the authorities to take action to ensure that all motorcycle and bicycle helmets available in retail and online stores meet Malaysian or international standards.

They also advised the public to exercise caution and make sure that they purchase motorcycle and bicycle helmets that are up to standard.

MMA said it would be invited by the Domestic Trade and Cost of Living Ministry in May to present the findings to the management group and discuss further steps towards protecting the public from unsafe helmets.

Advice from BikesRepublic.com

Implementation of the new SIRIM standard will be a much-welcomed development in terms of helmet safety, as several – if not all – local helmet manufacturers are still producing products that comply to the very old MS 1:1996 standard. For comparison, the European standard which is also adopted by the United Nations, is now ECE/UN R22.06 which came into effect this year. The previous ECE/UN R22.05 standard was implemented in 2000. So that shows you how old the current SIRIM standard is! There was a revision to the MS 1:2011 but not all local helmets comply to this.

Again, do buy and only wear helmets that were either approved by SIRIM (for locally produced helmets) and/or by ECE/UN R22.05 or ECE/UN R22.06 (for imported helmets). Solely DOT approved helmets are not approved for sale in Malaysia unless it has the additional ECE/UN approval.

The 2025 Triumph Trident 660 Special Edition has been revealed, as a tribute to the IoM TT (Isle of Man TT) Trident which won the races from 1971 to 1975.

Being a special edition, it is resplendent in the historic white, blue and red paint scheme with graphics, complete with number 67. This colour scheme was the colour on the TT-winning bike, dubbed “Slippery Sam.”

However, it is not just a paint scheme as Triumph has added some goodies that are otherwise only available as options. First, there is a colour matched flyscreen on top of the headlamp. Next, an aluminium belly pan underneath the engine, and Triumph Shift Assist quickshifter with auto blipper, as standard.

Other mechanical parts of the 2025 Triumph Trident 660 Special Edition remain unchanged. The engine is a 660cc triple which produces 80 hp at 10,250 RPM and 63.7 Nm of torque at 6,250 RPM. That is a huge 4,000 RPM spread between maximum torque and horsepower, meaning the engine pulls well anywhere in the RPM range!

The forks are still Showa upside-down, non-adjustable members, while the Showa monoshock at the rear is adjustable for preload only. Dual two-piston Nissin calipers up handle braking up front. Even the tyres remain unchanged from the Michelin Road 5.

Electronic features include ABS as standard, ROAD and RAIN riding modes, colour TFT screen, switchable traction control, immobiliser key security system.

Pricing starts from USD 8,595 (RM40,645.76) which is the same price as the standard Trident 660. However, there is different pricing in other countries, as it sells at a slightly higher price in Canada.

2025 Triumph Trident 660 Special Edition or also known as the 2025 Triumph Trident 660 Tribute will definitely make its way to Malaysia.

Only question we have is: Why didn’t Triumph launch a Daytona 660 Tribute instead?

A cargo ship hit a bridge and causing it to collapse, in Baltimore, USA. Reports estimated some 20 vehicles plunged into the river below.

A video making rounds on the internet showed the ship, Dali, losing power twice hence losing control. It was also apparent in the video that there was a large pall of black smoke from the ship’s smokestack when it came back to life after blacking out the first time, presumably due to the vessel’s pilot attempting to slow it further by hitting reverse in full power.

However, the Dali collided with one the Francis Scott Key Bridge’s supports, causing the bridge to snap in several sections.

There were also reports that the pilot aboard the ship had radioed a mayday to the port authorities stating that the ship was out of control. Unfortunately, authorities did not have enough time to respond to the emergency by shutting down traffic and clearing the bridge.

A pathway map published in The Virginian Pilot showed that the ship had travelled at a a mere 7 knots (13 km/h).

The tragedy occured at around 1.30am, local time, fortunately hours before the busy morning commute.

Search and rescue efforts are being carried out, but so far, only two people from a construction crew had been pulled out of the chilly water with six still unaccounted for.

The Dali left the Port of Baltimore to Colombo, Sri Lanka under the Singaporean flag. It is owned Synergy Marine Group and owned by Grace Ocean Private Ltd. but chartered by the Danish shipping conglomerate Maersk to carry their customers’ cargo. No Maersk crew and personnel were on board.

Opened in 1977, the bridge is named for the writer of America’s national anthem “The Star-Spangled Banner” and is a major roadway spanning the Patapsco River.

One of the biggest question asked among motorcycle owners is, “Does synthetic oil cause my engine to leak?”

The question is especially asked for those who own high mileage bikes (and cars), above 200,000km. But does it really happen?

What is synthetic oil?

To recap, a synthetic oil means its base oil was made from some source other than petroleum. “Base oil” on the other hand, refers to the origin of the oil before additives are added to it. There are several sources for synthetic base oils including PAO (polyalphaolefin) and ester.

A mineral base oil originates from refined petroleum, so synthetic base oil was synthesised.

The origins of this myth

The earliest synthetic engine oils were made from ester and entered the market in the early 80s. Prior to that, engine oils were mineral based.

1. Synthetic oil cleaned out sludge left by mineral oils

Sludge is that ultra sticky brown to dark brown goo, seen in poorly maintained and/or old engines. Once sludging has set in, getting them out is no easy task, even for the engine flush.

This sludge blocks gaps and holes in oil seals, stopping the oil from leaking.

Now, synthetic oils have better flow, detergence, and anti sludging properties which went ahead and cleaned out that sludge that stopped the leak. Therefore, the engine began to leak, when it was already waiting to leak in the first place.

It was not the oil’s fault, because a diligently maintained engine, regardless of age, is not supposed to leak at all.

2. Ester

Ester has some great properties such as resistance to high heat. However, the earliest ester-based synthetic oils were said to have caused oil seals to swell and break.

Oil producers have since overcome this by using better additives to counter that side-effect. This can be seen partly in oil service standards as it progressed from the earliest SA to SN, SN+, SP, SP+ now. The API service standard corresponds to an oil’s compatibility to the latest engine tech.

3. Synthetic oils have even sized molecules

Petroleum consists of many substances and that cannot be refined out completely. Some molecules are small, some are medium, and some are large.

As such, larger molecules will clog all the niches in the engine, including places or gaskets that have actually leaked. So when synthetic oil is used, it seeps through these gaps.

Conclusion

So, go ahead and use synthetic engine oil. I have been using it in my motorcycle and car, which both have gone above 200,000 km will no ill effect.
