ApexGrip Suspension Kit Series

The ApexGrip family transitions to a fully rebuildable damper cartridge architecture beginning with the 2025 model-year kits. Each cartridge incorporates a 24-click low-speed compression valve, 20-click rebound stack, and a three-position high-speed shim stack selected via an external hex key. The move eliminates factory-sealed units, allowing field service and custom valving without specialised presses. Spring sets now ship in two rate options—sport (linear 8.0 N/mm) and sport-touring (progressive 6.0–8.5 N/mm)—with colour-coded preload collars for quick visual confirmation. Internal oil volume increases by 12 %, extending service intervals to 30 000 km. A low-froth PAO-based 5 wt fluid is supplied pre-filled; the same part number is available in one-litre bottles for rebuild cycles. On-road evaluation covered 18 000 km across mixed surfaces. Telemetry logs highlight a 9 % reduction in mid-corner pitch variance and a 14 % decrease in front-wheel hop over segmented concrete compared with the outgoing kit. Rider feedback averaged 4.6 / 5 for compliance feel on an anonymised survey of 32 beta testers. Mounting hardware shifts to zinc-nickel coated Grade 10.9 bolts for improved corrosion resistance, and torque specs are laser-etched onto each yoke clamp to curtail workshop error. A downloadable setup worksheet auto-calculates sag based on rider weight and selected spring, exportable to PDF for customer records. Initial production covers the most common metric sport twins and triples; additional fitments enter release planning contingent on dealer demand. Retail pricing increases by 6 %, offset by the longer service life and rebuildability. Existing ApexGrip owners can order a retrofit cartridge bundle; installation requires only a bench vice, circlip pliers, and a 2 Nm in-lb wrench. Instructions and valve chart PDFs are live on the support portal today.

NitroPulse High-Flow Intake Kits

Version 3.0 of the NitroPulse intake platform introduces a modular velocity-stack set-up that lets riders switch between 38 mm, 45 mm, and 52 mm stack heights without removing the backing plate. The redesign centres on a cam-lock collar that secures each stack in 15 degrees of rotation, providing a tool-free change-over in under three minutes. CFD analysis guided a new bell-mouth geometry that improves air-stream laminarity; in controlled bench tests the coefficient of discharge (Cd) rises from 0.78 to 0.82. On-road instrumentation across four donor bikes shows intake-air temperature drops of 4 °C at 110 km/h cruise compared with the previous open-filter set-up, contributing to marginally richer AFR targets under steady-state load. Filter media moves to a dual-density synthetic matrix rated at 96 % efficiency down to 45 µm while maintaining service intervals of 15 000 km. For regions with heavy particulate, an optional pre-filter sock is now available. All kits ship with updated calibration tables for Bosch ME17 and Delphi MT05 ECUs; the tables are downloadable through the TorqueForge Flash utility (rev 1.6 or later). The backing plate is CNC-machined 6061-T6 aluminium with an anodised graphite finish; hardware is A2 stainless throughout. To curb packaging waste, stacks arrive nested, and the printed manual is replaced by a QR code linking to a multilingual PDF and video walk-through. Version 3.0 is in global distribution channels now, with SKU suffix “-NP3”. Owners of earlier NitroPulse versions may purchase individual stack modules separately; these are backward-compatible provided the latest cam-lock collar is fitted.

Street Thunder Exhaust Systems

The latest production run of Street Thunder slip-on and full-system exhausts is now shipping with a revised baffle architecture that reduces wide-open-throttle dB output by an average of 2.8 dBA while preserving the characteristically low-RPM growl riders have come to expect. The change follows the completion of homologation testing under the new UNECE R41-05 noise standard, enabling legal use in all EU member states without additional paperwork. Key technical adjustments include a dual-stage perforated-core wrapped in higher-density basalt wool, plus a minor taper to the exit cone that smooths pulse reflection. Flow bench data shows a 1.6 % increase in volumetric throughput at 8 000 rpm versus the previous model. Dyno validation on a 1200 cc V-twin platform indicates a repeatable 1.9 bhp gain at peak and a marginal torque lift of 0.8 Nm in the 3 200–3 800 rpm range. Finish options remain brushed stainless, mirror-polished, and matte-black ceramic. All units now ship with a replaceable dB-killer insert and a fresh set of high-temp Viton O-rings. Packaging has been downsized by 18 % to cut freight emissions; the cardboard is FSC-certified and fully curb-side recyclable. Dealers will begin receiving replenishment stock this week. End-users can verify batch authenticity via the laser-etched QR code on the mounting flange, which links to a digital installation guide and warranty registration. Existing owners retain upgrade eligibility at a discounted rate under the TorqueForge Continuous Improvement programme; contact customer support with proof of purchase for details.
