The SRK has the higher stated output and ABS; the TRX is less expensive, has a slightly lower seat and uses CBS. These are UK listing prices and specifications, not universal terms, and the listings do not establish that both bikes were newly launched in one announcement.

TRX 125: lower listed price and a slightly lower seat
The TRX 125 is listed at £2,299, with an 8.2 kW, 10 Nm air/oil-cooled engine and a five-speed gearbox. QJMotor specifies CBS rather than ABS, a 780 mm seat height, a 4-inch LCD, LED lighting and a 13.5 L tank. A 10 mm difference in published seat height may be useful when comparing dimensions, but it cannot establish whether either motorcycle will feel comfortable or manageable to a particular rider.
ABS and CBS are different stated braking systems; the specification pages do not provide comparative stopping tests. Do not treat the equipment list alone as evidence that one bike will stop better in every condition.

Prices, licensing and local availability
The £2,499 SRK and £2,299 TRX figures are prices on QJMotor UK product pages, accessed in 2026. They are UK-market listing prices, not a guarantee of the final amount payable. The TRX listing distinguishes its base price from on-the-road charges, which include items such as registration, road tax, pre-delivery inspection and delivery, but exclude insurance. Ask a UK dealer for a current, itemized quote; charges and availability can change.
The UK pages label these models A1/learner-oriented. That wording should not be assumed to describe licensing eligibility elsewhere: check the rules in your jurisdiction, as well as insurance terms, before buying.

QJMotor’s regional announcements are separate from the UK listings. On 19 February 2026, QJMotor France announced pricing for the SRT 125 DX, a trail-style 125cc model, at a French public price of €3,999 and stated availability in April 2026. The announcement describes distribution in France, Benelux and Switzerland through SIMA; it is not a price or launch announcement for the UK street bikes. QJMotor France had also said on 5 November 2025 that ten new vehicles were planned for France, Benelux and Switzerland, which does not establish a UK launch date for either SRK 125 S or TRX 125.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What to check before choosing
- Get an itemized, current dealer quote that separates the listed bike price from on-the-road charges and insurance.
- Confirm the version and equipment supplied in your market, especially braking system, display features and connected functions.
- Check local licence eligibility and insurance requirements rather than relying on the UK A1/learner label.
- Compare seat height in person if possible; the stated dimensions are a starting point, not a fit guarantee.
- Look for an independent road test or owner history if those matter to your decision. The official specifications cited here do not establish long-term reliability or real-world performance.
QJMotor UK’s new-bike lineup includes other 125cc categories as well, including scooters and trail/adventure models. The SRT 125 DX belongs to that separate trail category, not this street-bike comparison.
