The renowned bike modders at Sinroja Motorcycles are best known for their amazing BMW projects, but they’re also willing to step outside their comfort zone from time to time. Under Rahul Singhroja’s leadership, the Leicester-based company could probably do wonders on just about any brand of bike if required. Case in point, the evil Scrambler shown below is a far cry from the German boxers they usually build.
In contrast, it started with one of Triumph’s modern classics, specifically the bone stock Bonneville SE. Considering the stylistic direction the British shop was trying to take, you might think it would make more sense to go with the Scrambler model. While this is certainly true, Rahul and his team don’t like to take the easy and obvious path when it comes to one-off epic pieces.
The surviving Bonnie served as the daily commuter for Shinroha’s crew. In 2019, they decided to customize the bike for the Mull Mill Festival, an annual gathering celebrating the Midlands’ motorcycle culture. This was the original plan to proceed, but as the transformation process progressed, plans changed.
While Bonneville operated on his workbench, eager customers visited the company’s headquarters. What happened next was a matter of love at first sight. Because he decided to buy the in-progress build right away, before it was even close to completion. Confident in Sinroja’s abilities, the client had no intention of interfering with their already established creative vision, choosing instead to sit back and be left to their own devices.
This was clearly a very inspired decision, and Rahul’s experts paid huge dividends while keeping things relatively simple and budget-friendly. Without further ado, let’s take a look at how they transformed a stock Bonneville into a stealth-looking scramble centerpiece. The extensive use of premium components from TEC Bike Parts is one of the most notable aspects of this model.
At the front end, the fork was rebuilt with new internals and preload adjusters from TEC’s catalog, while the suspension mods were more extensive. Shinroha has completely scrapped the donor’s factory shock absorber and replaced it with a high-spec piggyback replacement sourced from the same aftermarket brand. Once the suspension work was completed, they looked into the footwear department.
The Bonneville’s original seven-spoke wheels are still there, but have been sandblasted and repainted with a layer of satin black. They then covered the rims with rugged dual-purpose TKC 80 knobs provided by Continental. Additionally, the front fenders have been trimmed to reduce visual weight without sacrificing practicality, but the rear mudguard is nowhere to be seen.
If you thought we had a complete list of all the TEC parts used in this build, think again. The company also neatly installed a compact tail where the standard rear fender used to be, and the multi-function LEDs on the sides are top-grade His Rizoma goodies. Once again he turned to TEC solutions. Sinroja ordered a prefabricated skid plate with circular cutouts, similar to the modules seen in some of Tamarit Motorcycles’ projects.
The new saddle was sourced from Triumph’s own aftermarket stock, and the factory SE fuel tank remains intact. However, the knee pads, badging, and original paint were removed and it was finished in metallic black with gunmetal gray graphics. The Monza-style flip-up filler cap is brought to you by – surprise, surprise – TEC Bike Parts and takes top spot. Further down the side of Bonnie is a set of replacement side panels.
Rear-mounted footpegs from TEC also make an appearance, and the rear brake is operated via a repurposed master cylinder from the BMW R 100 RS. A new drive chain and included sprocket complete the rear outfit of this creature, but there’s more to talk about up front. We’re talking about bright LED headlamps supported by handmade mounting hardware, and front-end turn signals attached to triple clamps at the bottom.
With the customization process nearing completion, Sinroja Motorcycles moved on to work on the powertrain side. They gave the parallel twin mill a youthful air filtration fixture and a refreshing internal cleanup before turning their attention to the exhaust. In place of the SE’s standard plumbing, you’ll see a high-mounted aftermarket setup that performs a 2-in-1 configuration.
Constructed from stainless steel, it is fitted with two heat shields to prevent temperatures near the rider’s legs from getting too hot. The engine cover is all his OEM parts, but has been painted matte black to match the rest of the car.Even if Shinroha’s results weren’t all that strange. conversionwe can all probably agree that their scrambled Bonnevilles are a thrilling sight to behold.
