Custom Triumph Bonneville Keeps the Scrambler Recipe Simple But Undeniably Effective

Under the leadership of Rahul Sinroja, the Leicester-based firm would probably be able to work wonders on bikes from just about any marque if necessary. Case in point, the sinister scrambler shown below is far from the German boxers they normally build.

By contrast, it started with one of Triumph’s modern classics, more specifically a bone-stock Bonneville SE. Given the stylistic direction that the UK shop was looking to take, you might think it would’ve made more sense for them to use a Scrambler model. This would indeed be correct, but Rahul and his squad don’t like taking the easy or obvious route when it comes to their majestic one-offs.

In its stock incarnation, the Bonnie served as a daily commuter for the Sinroja crew. Come 2019, the guys decided to have it customized for the Malle Mille festival, which is an annual gathering celebrating motorcycle culture in the Midlands. Although this is how things were initially meant to go, a change of plans took place as the transformation process was unfolding.

An eager client visited the firm’s headquarters while the Bonneville was on their workbench undergoing surgery. What happened next was a matter of love at first sight, because he immediately decided to buy the ongoing build before it was even close to completion. Confident in Sinroja’s abilities, the customer had no intention of intervening in the creative vision they’d already established, instead opting to sit back and leave them to their own devices.

This was clearly a very inspired decision, one which Rahul’s specialists rewarded in spades while keeping things relatively simple and budget-friendly. Without further ado, let’s dive in and see how they’ve turned the stock Bonneville into a scrambled showstopper with stealthy looks. The extensive use of premium componentry from TEC Bike Parts is one of the most notable things about this specimen.

At the front end, the forks were rebuilt with fresh internals and preload adjusters from TEC’s catalog, but the suspension mods were even more extensive out back. Sinroja ditched the donor’s factory shock absorbers altogether, replacing them with higher-spec piggyback alternatives sourced from the same aftermarket brand. Once the suspension-related work was out of the way, they had a gander down at the footwear department.

Whereas the Bonneville’s original seven-spoke wheels are still present, they’ve been sand-blasted and repainted in a layer of satin-black. Then, the lads cloaked their rims in a beefy pair of dual-purpose TKC 80 knobbies supplied by Continental. In addition, they trimmed the front fender to reduce visual heft without sacrificing practicality, but the rear mudguard is nowhere to be seen.

If you thought we were done listing all the TEC parts used on this build, think again. The company also provided the compact tail tidy mounted where the standard rear fender had once been, while the multi-function LEDs found on the flanks are top-grade Rizoma goodies. Once again turning to TEC solutions, Sinroja ordered an off-the-shelf skid plate with circular cut-outs, similar to the modules we’re seen on some projects from Tamarit Motorcycles.

The new saddle came from Triumph’s very own aftermarket inventory, and the factory SE fuel tank has been retained. However, it was stripped of its knee pads, badges, and original paintwork, then finished in metallic-black with gunmetal-grey graphics. A Monza-style flip-up filler cap takes pride of place up top, provided by – surprise, surprise – TEC Bike Parts. Further back on the Bonnie’s flanks, we come across a set of replacement side panels.

Rear-mounted foot pegs from TEC also make an appearance, with the rear brake getting actuated via the repurposed master cylinder of a BMW R 100 RS. A fresh drive chain and accompanying sprockets finish off the creature’s equipment at the rear, but there’s more for us to talk about up front. Namely, we’re referring to a bright LED headlamp supported by handmade mounting hardware, while the front-end blinkers sit on the lower triple clamp.

With the customization process nearing completion, Sinroja Motorcycles moved on to the powertrain side of things. They treated the parallel-twin mill to some youthful air filtration paraphernalia and an invigorating internal clean-up, before turning to the exhaust. Instead of the SE’s standard pipework, you will now see a high-mounted aftermarket setup running a two-into-one configuration.

It’s made of stainless-steel and fitted with two heat shields to prevent temperatures from getting too toasty near the rider’s leg. All the engine covers are still the OEM parts, though they’ve been painted matte-black to match the rest of the build. Even if there is nothing too crazy about the result of Sinroja’s transformation, we can probably all agree that their scrambled Bonneville is a thrilling sight to behold!
