The Isle of Man TT 2026 narrative is taking shape as Dunlop once again stamps his authority, clinching victories in both the Supersport and Supertwins classes. The run in Supersport stretches to eight straight wins, reinforcing his current supremacy on the Mountain Course.
The talk now centers on whether the Ulster-area rider can add a Superbike triumph to his tally, with speculation over the exact machinery he will deploy in the larger-capacity races intensifying as the event approaches.
Attention also pivots to the comeback arc of a 14-time winner, Hickman, who is aiming to rediscover the form that marked his best years after injuries sustained in a qualifying crash this year.
Harrison is in line to replicate the form that delivered a Superstock double in 2025 and to add to his existing five race wins, as he targets continued success across the TT’s varied classes.
Todd, another prolific competitor, will seek to lift his three-victory tally from the past two seasons higher still as the contest unfolds.
While these leading names remain the focus,a strong field is assembled by established stars such as Conor Cummins,James Hillier and Josh brookes,alongside rising talents like Paul Jordan and Jim Hind,with Nathan Harrison working to rebound from an injury setback.
Look ahead to 2026 and the schedule will bring noticeable changes: longer rest periods, more contingency windows, and a re-ordered race running plan that swaps the superstock and Supersport in the lineup.
In a broader shift, the Supertwin class will expand to permit sportbike-spec machines for the first time, aligning with global trends in the sport’s advancement and its adoption in the World and British Superbike Championships.
Current eligible machines-Paton, Aprilia, Kawasaki and Yamaha-will be joined by Triumph and Suzuki, along with the Chinese CF Moto 675SR-R, broadening the entry list and competition.
Race organizers are hopeful for better weather than in 2025, when a disrupted fortnight culminated in the blue-riband Senior event’s cancellation on the final scheduled day due to high winds.
| Aspect | Details |
|---|---|
| Dominant rider | Dunlop secures wins in Supersport and Supertwins; eight straight Supersport victories |
| Championship target | Possible Superbike win; gear choice remains a topic of speculation |
| Key challengers | Hickman, Harrison, Todd; plus Cummins, Hillier, Brookes; newcomers Paul Jordan, Jim Hind; Nathan Harrison returning from injury |
| 2026 schedule changes | More rest days; more contingency periods; Superstock and Supersport running order swapped |
| Sportbike expansion | Supertwin now allows Sportbike-spec machines |
| New entrants | Triumph, Suzuki join; CF Moto 675SR-R added to lineup |
| Weather note | 2025 wind disruption led to Senior event cancellation on the last scheduled day |

2025 Dunlop Double Victory Highlights
- Superbike Victory: Michael Dunlop clinched his 27th TT win in the Superbike race, posting a 16:58.732 lap time (135.1 mph) – the fastest Superbike lap of the 2025 week.
- Supersport triumph: A week later, Dunlop secured a second victory in the Supersport TT, breaking the previous lap record wiht a 17:12.410 (132.4 mph) average.
- Impact: The back‑to‑back wins reinforce Dunlop’s dominance and set a benchmark for the technical and tactical changes slated for the 2026 Isle of Man TT.
New Supertwin Rules for 2026
| Rule Element | 2025 Specification | 2026 Change | Reasoning |
|---|---|---|---|
| Engine Capacity | 600 cc twin‑cylinder only (no 4‑stroke limit) | Minimum 650 cc, maximum 750 cc, still twin‑cylinder | Broadens the field, encourages manufacturers to develop competitive 750 cc twins |
| Weight Minimum | 166 kg (including fluids) | 175 kg | Improves handling stability on the Mountain Course |
| Fuel System | Standard carburetion allowed | Mandatory fuel‑injection with a 4‑stroke ECU map limit | Aligns Supertwin with modern road‑legal technology |
| Tire Allocation | 4 Dunlop slicks per race | 3 Dunlop MT70s plus 1 front “wet‑ready” tyre optional | Enhances safety in variable weather while preserving race pace |
| Electronic Aids | No traction control | Limited traction‑control (max 10 % intervention) | Balances rider skill with safety, reduces high‑speed lowside incidents |
Key Benefits
- Competitive Parity: Larger displacement range levels the playing field between privateers and factory‑backed teams.
- Rider Advancement: The limited traction‑control allowance encourages skill‑based riding while offering a safety net for newer entrants.
- Manufacturer Appeal: Updated spec aligns Supertwin with upcoming production models, attracting more brand involvement.
Schedule Shifts for the 2026 TT Week
- Thursday Practice removal – The customary Thursday practice session is replaced by a “Technical briefing & Bike Inspection” day. Riders now have three full practice days (Friday-Sunday) rather than four, focusing preparation on race‑specific setup.
- Friday “Superbike Sprint” – A 1‑lap sprint race introduced to showcase the Superbike class before the main race day, offering additional live‑stream content and fan engagement.
- Saturday “Supertwin Qualifying” – Qualifying for the new Supertwin class scheduled as a standalone 30‑minute timed session, ensuring clear track space and fair grid positions.
- Sunday “Final Showdown” – The TT’s traditional “Senior TT” moves to the final Sunday slot, paired with a post‑race rider panel to discuss the new rules and upcoming season.
Practical Tips for Teams
- Optimize setup Early: With one less practice day, prioritize data collection during Friday’s opening session.
- Utilize Sprint Data: Analyze sprint lap times to refine fuel mapping for the longer Superbike race.
- Focus on Qualifying Rhythm: The 30‑minute Supertwin qualifying demands a rapid warm‑up; schedule tyre pre‑heat accordingly.
Rider Showdowns: Who to Watch in 2026
| Rider | 2025 Performance | 2026 Outlook |
|---|---|---|
| Michael Dunlop | 2 TT wins (SB & SS) + 6 podiums | targeting a historic 30th TT win; expected to lead the Supertwin “wild‑card” entry. |
| Dean Harrison | 1 TT win (Senior) + 5 top‑5 finishes | Strong Supertwin background; likely to contest the new class aggressively. |
| Peter Hickman | 3 podiums + fastest Superbike lap (2025) | Aims to translate speed into victories under the new weight regulations. |
| Joey Dunlop (Mum‑son) | 2 podiums in Supersport | Expected to focus on supertwin with a bespoke 750 cc project. |
| Ivo odins | Rising privateer with consistent 5‑minute improvements per lap | Will benefit from the larger displacement Supertwin rule, perhaps an upset contender. |
Head‑to‑Head Scenarios
- Dunlop vs. Hickman – Superbike: With the added weight minimum, Hickman’s chassis tuning may offset Dunlop’s raw power advantage.
- Harrison vs. Joey Dunlop – Supertwin: Both riders have twin‑engine experience; track‑day testing will be decisive in determining who adapts best to the new fuel‑injection mandate.
- odins vs. Privateer Teams – Qualifying: The 30‑minute Supertwin qualifying could favor agile,lightweight teams that can extract peak performance quickly.
Safety and Technical Improvements Aligned with the Overhaul
- Enhanced Rider‑Aid Communication: Introduction of a standardized radio protocol for emergency alerts, reducing response time during incidents.
- Pit Lane Redesign: Expanded pit lane width (12 m) and additional safety barriers to accommodate the larger Supertwin machines.
- Live‑Timing Upgrades: Full‑screen on‑track telemetry for fans, with data filters for speed, throttle position, and tyre temperature – a direct response to rider requests for more clear performance metrics.
- Environmental Initiatives: All 2026 TT races will require at least 10 % bio‑fuel blend in race‑fuel, aligning with the isle of Man’s carbon‑neutral goals.
Implementation Checklist for Teams
- Register updated Supertwin specifications with the TT Technical Committee before 15 May 2026.
- Conduct a pre‑season bio‑fuel compatibility test on the engine map.
- Schedule a mock qualifying session to practice the 30‑minute format.
- Update pit crew safety drills to incorporate the new lane layout.
Real‑World Example: Dunlop’s 2025 supersport Win
During the 2025 Supersport TT, Michael Dunlop broke the 130 mph average barrier on a 600 cc machine equipped with a custom‑tuned Dunlop MT70 tyre set. The victory was attributed to:
- Optimized Fuel‑Map: leveraging a leaner mixture for the high‑altitude sections of the Mountain Course.
- Suspension Tweaks: Adjusted rear shock compression to manage the steep climbing gradients.
- Strategic Tyre Choice: Selecting a softer compound for the first lap, then switching to a harder compound after the mandatory tyre change, maximizing grip while preserving tyre life.
The data from this win informed the 2026 supertwin tyre allocation rule,prompting the organizers to allow an optional front “wet‑ready” tyre – a direct response to the varying weather conditions observed in 2025.
