Delhi based High Note Performance has announced that it will be importing the S&S exhaust system for the Royal Enfield 650 Twins. Regular readers would know that Royal Enfield already offers S&S exhaust with the Interceptor INT 650 and the Continental GT 650 in select international markets, although the same system is not available in our country.
High Note Performance offers safety gear, accessories and parts for motorcycles. The store made the announcement about the pre-orders for the S&S exhaust system via its Instagram handle. The availability dates and prices are yet to be announced. While the promotional image states "S&S Exhaust for Interceptor INT 650", the aftermarket part can also be installed on the Continental GT 650.
The aftermarket exhaust will further enhance the sound from the parallel twin-cylinder engine with 270-degree firing order. Several local brands also offer aftermarket exhausts for the 650 Twins. We have already seen aftermarket exhaust systems from brands like Red Rooster Performance, AEW and Grid7, among others. However, the most attractive exhaust, which we saw for the 650 Twins, came from Termignoni. The Italian manufacturer revealed a scrambler-style exhaust system for the Interceptor INT 650 last month.
While the store in Delhi will only import the exhaust system, S&S Performance also offers several parts such as Big Bore Kit for the 650 Twins in the international markets. As reported earlier this month, the Big Bore Kit boosts the displacement of the Interceptor INT 650 and the Continental GT 650 to 865 cc. The kit comprises pistons, cylinders and a head gasket.
For reference, the 648 cc, fuel injected, parallel-twin cylinder, air & oil cooled, SOHC engine makes 47 bhp at 7,250 rpm and 52 Nm of torque at 5,250 rpm in stock form. The added displacement would enhance the performance numbers, although the power and torque output numbers post the Big Bore Kit are not available yet. Do note that the Big Bore Kit is for closed course competition use only.
In other updates, Royal Enfield will soon update the ECU on the 650 Twins to address the high altitude performance issues reported by some owners. The software update, which has been approved by ARAI, will come pre-installed on all Interceptors and Continental GT motorcycles manufactured after June. Existing owners will also receive the update from authorised Royal Enfield service centres.
