The number of aftermarket exhausts for the Royal Enfield 650 Twins has been extended with the addition of a new option. Officially, Royal Enfield offers S&S exhaust system as an optional accessory with the 650 Twins. However, that exhaust is not available in the Indian market. The first aftermarket exhaust for the 650 Twins arrived from Red Rooster Performance back in December 2018, which was soon followed by a unit from Grid7 Customs.
Visually, the exhaust does not look drastically different from the stock units although the stock unit has a chrome finish. Similar to the exhausts from Red Rooster Performance and Grid7 Customs, the new unit adds a throaty note to the 650 Twins.
Should you buy one? Aftermarket exhausts do add a nice aural upgrade to the motorcycles, but they do tend to get you into trouble with the lawmakers. It also tends to void the warranty of the bike and thus, we recommend you to consult a Royal Enfield service centre before making any mechanical changes.
Regular readers would know that Royal Enfield has used a parallel-twin cylinder engine on the 650 Twins that features a single-piece forged counterbalanced crankshaft with 270-degree firing order. The setup provides a V-twin-like character to the exhaust note and minimises vibrations. The aftermarket exhaust further enhances the exhaust note. The 648 cc parallel-twin, air-cooled engine delivers 47 bhp of maximum power at 7,250 rpm and 52 Nm of peak torque at 5,250 rpm.
In more updates from the brand, Royal Enfield is busy updating its portfolio to comply with the upcoming safety norms. The company launched the Bullet 500 ABS in India this month while the 350 cc variant will receive the update in February. The steep hike in prices due to increased insurance rates, ABS upgrade costs and the return of Jawa motorcycles are troubling Royal Enfield as the sales witnessed negative growth in November and December 2018. It has led to an increase in the inventory, and thus the Chennai-based two-wheeler brand would reportedly cut production.
